how to erase negative ticks from NVD3 line chart - javascript

I tried to erase negative ticks from my NVD3 line chart (with data includes 0 only)
but It seems impossible what I wanted to do...
I want to set the line bottom when I throw data what includes 0 only.
Is there another way? or just I had a mistake?
code:
nv.addGraph(function() {
//DATA.B includes only 0 data, the value must be "data>0"
data = DATA.A,DATA.B;
var chart = nv.models.linePlusBarChart()
.margin({top: 30, right: 60, bottom: 50, left: 70})
.x(function(d,i) { return i })
.y(function(d,i) { return d[1] });
chart.xAxis.tickFormat(function(d) {
var dx = data[0].values[d] && data[0].values[d][0] || 0;
return d3.time.format('%Y-%m-%d')(new Date(dx))
});
chart.y1Axis
.tickFormat(d3.format(',f'))
.tickSize(0,6);
chart.y2Axis
.tickFormat(function(d) { return d3.format(',f')(d) + '%' });
chart.bars.forceY([0]);
d3.select($node).datum(data).transition().duration(0).call(chart);
nv.utils.windowResize(chart.update);
return chart;
});
thanks

show row chart after clicking a other chart (dc.js)

I have two row charts and need to show the 2nd chart after i clicked (selectetd one) on the first row chart. how can i make it?
I can't add a js fiddle, because i'm getting my data from a database.
var TestCaseRow = dc.rowChart("#TestCaserowchart");
var TestCaseDim = perfData.dimension(function (d) {
return d.TestCase;
});
var clickGroup = TestCaseDim.group().reduceCount(function (d) {
return d.x;
});
var filtered_groupTestCase = remove_empty_bins(clickGroup);
TestCaseRow
.width(1100)
.height(filtered_groupTestCase.all().length*18)
.margins({ top: 5, left: 10, right: 10, bottom: 20 })
.dimension(TestCaseDim)
.group(filtered_groupTestCase)
.elasticX(true);
//my other row chart
var testscriptRow = dc.rowChart("#testscriptrowchart");
var testscriptDim = perfData.dimension(function (d) {
return d.TestScript;
});
var ClickTestscriptGroup = testscriptDim.group().reduceCount(function (d) {
return d.x;
});
var filtered_groupTestScript = remove_empty_bins(ClickTestscriptGroup);
testscriptRow
.width(1100)
.height(filtered_groupTestScript.all().length*40)
.margins({ top: 5, left: 10, right: 10, bottom: 20 })
.dimension(testscriptDim)
.group(filtered_groupTestScript)
.elasticX(true);
Register an event-handler on the first chart with .on('filtered', function(chart, filter){...}). Within that function, check if the 2nd chart is displayed and if it is not, do whatever you need to do to display it.

How to hide first Y Axis line on an nvd3 chart?

Plnkr example:
http://plnkr.co/edit/19D5cnrVYdUrMlblQARy?p=preview
Screenshot from my app:
I've tried modifying the CSS, however I was only able to remove the 2nd (right Y axis line), but not the first left Y axis line.
What I've tried:
.nv-y {
display: none;
}
As well as all the lines from this answer: Alter first vertical grid line in nvd3
d3.selectAll('.nv-y').attr('display','none')
d3.selectAll('.nv-y path').attr('opacity','0.1')
d3.selectAll('.nv-y path').attr('display','none')
My current drawChart function:
function drawChart(res) {
console.log(' ');
console.log('drawChart res = ',res);
nv.addGraph(function() {
var chart = nv.models.linePlusBarChart()
.margin({top: 30, right: 40, bottom: 50, left: 40})
.x(function(d,i) { return i })
.y(function(d) { return d[1] })
.color(d3.scale.category10().range());
chart.xAxis.tickFormat(function(d) {
var dx = res[0].values[d] && res[0].values[d][0] || 0;
return d3.time.format('%x')(new Date(dx))
});
chart.y1Axis
.tickFormat(d3.format(',f'));
chart.y2Axis
.tickFormat(function(d) { return '$' + d3.format(',f')(d) });
chart.bars.forceY([0]);
// https://stackoverflow.com/questions/23754188/nvd3-js-how-to-disable-tooltips-for-one-serie-only
chart.lines.interactive(false);
// http://nvd3-community.github.io/nvd3/examples/documentation.html#line
chart.height(280);
// If not chart data is avaliable to display:
chart.noData("There is no Data to display at the moment.");
// Remove legend:
chart.showLegend(false);
d3.select('#chart svg')
.datum(res)
.transition().duration(500)
.call(chart);
d3.selectAll('.nv-y path').attr('display','none');
nv.utils.windowResize(chart.update);
return chart;
});
}
if you want to hide the 1st y axis do:
.nv-y1{
display:none;
}
if you want to hide the 2nd y axis do:
.nv-y2{
display:none;
}

Use this :
.domain {
display: none;
}

nvd3 multiple charts sharing the same data

I am trying to build 2 vertical charts sharing the same data. So I created a refreshPrimary(top) and refreshStackedArea(bottom) that can be called to refresh the graphs depending on options the user selects.
The problem I am having it that when I invoke both refreshPrimary and refreshStackedArea the top graph does not show.if I only do refreshPrimary it display it's graph ok. Below are the refresh functions, the HTML and chart drawing functions.
Refresh function :
// Add refresh function to lm_pareto context
function refreshPrimary() {
//
function refreshGraph() {
console.log("DEBUG JS lm_pareto.refreshGraph entered");
d3.selectAll("#lm_pareto svg > *").remove();
d3.select('#lm_pareto svg')
.datum(lm_pareto.dataPrimary)
.call(chart);
//Update the chart when window resizes.
nv.utils.windowResize(function() { chart.update() });
return chart;
}
nv.addGraph(refreshGraph);
}
function refreshStackedArea() {
function refreshGraph_SArea() {
d3.selectAll("#lm_stackedArea svg > *").remove();
d3.select('#lm_stackedArea svg')
.datum(lm_pareto.dataStackedArea)
.call(chart); //Finally, render the chart!
//Update the chart when window resizes.
nv.utils.windowResize(function() { chart.update() });
return chart;
}
nv.addGraph(refreshGraph_SArea);
}
HTML DIV's
<div id="lm_pareto" class="lm_graph" style="border: 2px solid blue"></div>
<div id="lm_stackedArea" class="lm_graph" style="border: 2px solid blue"></div>
TOP CHART
var chart;
nv.addGraph(function () {
chart = nv.models.stackedLineChart()
.options({
reduceXTicks: false
})
.margin(margin)
// Get normalised data for chart
chart.lines1.forceY(0);
chart.lines2.forceY(0);
svg = d3.select("#lm_pareto")
.append("svg");
// chart is a temp object of nv.addGraph... not able to pass back.
return chart;
});
BOTTOM CHART
var margin = {
top: 50,
right: 50,
bottom: 50,
left: 70
};
var chart;
nv.addGraph(function() {
chart = nv.models.stackedAreaChart()
.margin(margin)
.x(function(d) { return d[0] })
.y(function(d, x) { return d[1]; })
.useInteractiveGuideline(true)
.rightAlignYAxis(false) //y-axis to the right side.
// .transitionDuration(500)
.showControls(false)
.clipEdge(true)
.color(lm_pareto.ColorList);
chart.yAxis
.tickFormat(d3.format(',.2f'));
svg = d3.select("#lm_stackedArea")
.append("svg")
// OLD WAY
//svg.datum(lm_pareto.dataStackedArea)
// .call(chart);
//
//nv.utils.windowResize(chart.update);
return chart;

nvd3 lineplusBarChart add values from javascript

I have this code to produce a lineplusBarChart
HTML
<div id="chart1" class='with-3d-shadow with-transitions'>
<svg> </svg>
</div>

testdata[0].values.push([time, quantity]);//NOT SHOWING THE BAR
var chart;
nv.addGraph(function() {

chart.dispatch.on('stateChange', function(e) { nv.log('New State:', JSON.stringify(e)); });
return chart;

</script>
Now i want to add some variables to the graph from javascript. Let say i have two variables var time="1134345600000" and var quantity="12332212". i want some how to push these two variables into var testdata.values.
Is there an possible way?
DEMO (js code after line 23240)
In your particular case, you need to push the data like this:
testdata[0].values.push({x: +time, y: +quantity});

python-nvd3 lineplusbarwithfocus chart error

I was trying to use python-nvd3's linePlusBarWithFocusChart in one of my projects. But the y4 data, the data on the focus bar shows up something like this:
http://i.stack.imgur.com/ntJNW.png
As you can see the data is not represented right. Following is the generated script:
<script type="text/javascript">
nv.addGraph(function() {
var chart = nv.models.linePlusBarWithFocusChart();
chart.margin({top: 30, right: 60, bottom: 50, left: 70})
.x(function(d,i) { return i });
chart.height(350);
chart.color(d3.scale.category10().range());
chart.y2Axis
.tickFormat(function(d) { return d3.format(',.2f')(d) });
chart.x2Axis
.tickFormat(function(d) {
var dx = data_linePlusBarWithFocusChart[0].values[d] && data_linePlusBarWithFocusChart[0].values[d].x || 0;
return d3.time.format('%d %b %Y')(new Date(dx));
});
chart.y4Axis
.tickFormat(function(d) { return d3.format(',.2f')(d) });
chart.y3Axis
.tickFormat(d3.format(',f'));
chart.xAxis
.tickFormat(function(d) {
var dx = data_linePlusBarWithFocusChart[0].values[d] && data_linePlusBarWithFocusChart[0].values[d].x || 0;
if (dx > 0) { return d3.time.format('%d %b %Y')(new Date(dx)) }
return null;
});
chart.y1Axis
.tickFormat(d3.format(',.4f'));
chart.bars.forceY([0]);
chart.tooltipContent(function(key, y, e, graph) {
var x = d3.time.format('%d %b %Y')(new Date(parseInt(graph.point.x)));
var y = String(graph.point.y);
if(key.indexOf('Sentiment Rate') > -1 ){
var y = String(graph.point.y) ;
}
if(key.indexOf('User Rating') > -1 ){
var y = String(graph.point.y) ;
}
tooltip_str = '<center><b>'+key+'</b></center>' + y + ' on ' + x;
return tooltip_str;
});
chart.showLegend(true);
d3.select('#linePlusBarWithFocusChart svg')
.datum(data_linePlusBarWithFocusChart)
.transition().duration(500)
.attr('height', 350)
.call(chart);
return chart;
});
</script>
The code that was used to generate the above script is:
type = "linePlusBarWithFocusChart"
chart = linePlusBarWithFocusChart(name=type, height=350, x_is_date=True, x_axis_format="%d %b %Y",
color_category="category10")
kwargs = {}
kwargs['bar'] = True
extra_serie = {"tooltip": {"y_start": "", "y_end": ""}}
chart.add_serie(name="", y=ydata, x=xdata, extra=extra_serie, **kwargs)
extra_serie = {"tooltip": {"y_start": "", "y_end": ""}}
chart.add_serie(name="", y=ydata2, x=xdata, extra=extra_serie)
chart.buildhtml()
Could anyone tell me what am I doing wrong!!
The data in your context chart looks like it's simply out of order. All you need to do is sort the data before you pass it to NVD3.
