I would like to display gaps in a chart serie. I'm using Sencha Touch 2.4.1. I already tried to set the data to "no data" which results in a solid line between the surrounding data records (Sencha Fiddle). Setting the data to null results in a zero value in the chart.
Is there a way to display a gap in the serie?
Try the following fiddle: https://fiddle.sencha.com/#fiddle/lb9
It uses renderer to define transparent color for some parts of the chart. More information you can find here: http://docs-origin.sencha.com/touch/2.4/2.4.1-apidocs/#!/api/Ext.chart.series.Line-cfg-renderer

I cannot find a way to make showValues: '1' show the data plot values in a zoomline graphic with Fusion Charts.
You see and try it in this fiddle: http://jsfiddle.net/60oeahc1/4/
¿Is there a way to make it work for zoomline charts?
The thing is that with a line chart is working: http://jsfiddle.net/z0xutjhL/
As per your query, since zoomline features large data , using showValue would overlap the data value text which in turn will result in poor visualization. Hence, It will not be possible to use showValue here.

There is a very nice graph and pie chart under Investment Decision-Making in 2016.
I know it is highcharts now. I want to write something similar. But I can't find any chart type similar in its document.
Could you tell me what kind of chart it is? And how to put different data items inside the bubble.
It looks like a combination of line, bubble and pie series.
Line series (alternative: scatter with lineWidth > 0) lies under the bubbles. All interaction with this series should be disabled (hover state, tooltip, etc.).
Text inside the bubble is data label (dataLabels.enabled property should be set to true). You can manage its content in dataLabels.formattercallback function.
You can handle showing/adding pie (donut) charts in plotOptions.bubble.point.events.mouseover callback function. Text in the middle of a donut can be rendered via SVGRenderer.text().
All options that I mentioned can be found in the API: https://api.highcharts.com/highcharts/
function chart (data, selector) {
// generate chart with zoom feature. it scales the X domain and update the chart accordingly.
}
chart(dataset1, "#chart1")
chart(dataset2, "#chart2")
chart(datasetn, "#chartn")
the code above is a chart generator function which I give it different datasets to make me charts. in all charts, the dataset has the same X values but different Y values.
problem:
lets say we have 3 charts, all the X axis ranges are between 0-100. In the first chart, I drag mouse and create a zoombox between 30-60 and the first chart updates, now it is scaled between 30-60. But the second and third chart are intact. I need them to be updated as well between 30-60.
similarly if I do the same for second chart, I need the first and third one get updated.
here is jsfiddle to illustration
I made not so big modification to make this works.
First of all we remember globally the information about single chart in var charts array. This is done during creation of charts
charts.push(lineChart(data1,"#chart1"));
charts.push(lineChart(data2,"#chart2"));
charts.push(lineChart(data3,"#chart3"));
Next we can use this array in function zoomdrag and update.
This work maybe not perfect (reset of chart is missing) but show how to handle it and get the same zoom in all charts.
Here is jsfiddle
I need to draw a graph to display engine status.That is i will be having time like 1-2,2-3,3-4 along axis and by using bar graph i need to display whether engine was on or off at these time.
That is from 1-2 if it is off it will how black and 2-4 if it is on it will show blue color and again if the status is changed it should show black from blue.Right now i have customised jquery high charts for displaying one bar,by removing some parameters.
I need to know how i implment this here or is it possible in this graph?
You can do this with a column range chart, with minimal fudging.
The main issue is making sure you set your data points correctly, and to set grouping:false in the plotOptions. The x value needs to be specified for each data as well, or else they will all be given a separate x value
Example:
http://jsfiddle.net/jlbriggs/o9ck2zLn/
This can easily be adapted to a time axis by supplying the timestamps as the y values.
So I'm generating bar chart in D3.js with a csv file a la the basic columns example. What I want to do is show just one bar at a time for each row of data. A JQuery-like slider will iterate over the csv rows and update the chart. For the user, it'll just look like the single bar's height is changing but the x axis should update with the date as well.
Here's an example of the data that I'll be feeding into it:
DATE,INFLOW (CF),OUTFLOW (CF),STORAGE (CF)
20120101,950400,28857600,11084277600
20120102,60912000,28771200,11099959200
20120103,56505600,28857600,11130451200
20120104,55900800,28771200,11158765200
20120105,55987200,28771200,11189692800
20120106,56419200,28771200,11220620400
20120107,55123200,28684800,11246756400
The only thing I actually want to show is DATE and STORAGE (CF). So I'll probably have to do some parsing of the CSV somewhere to get it in the best shape.
I've attempted this and would post some code but all of my attempts are a mess. I can generate a plausible bar chart with all of the rows at once, but when I attempt to show a single one, everything breaks. Here are the challenges that I could use some guidance one:
How to splice or filter my csv with a slider so that only a single row is selected
Best way to generate a bar chart that only has a single bar from a single row in a csv (every time I try to do this I have trouble with axes and accessing the array values correctly)
Best way to update the bar, changing only height but also updating the x axis ticks
Also any examples would be very helpful! Have been googling like mad but am mostly finding sliders that affect range and scale
There are many pieces to this...parsing and slicing the data, setting up the x axis, etc. Here is one segment of the code.
d3.select("#slider")
.on("input", function() {update(+this.value);});
function update(row) {
viewdata = data.slice((row-1), row);
redraw();
}
Here is a complete PLUNK with the solution. NOTE: I have placed comments in several parts of the code, for orientation. I strongly suggest you fork this plunk so that it will not be lost if I inadvertently delete it.
