Antd Charts - Area chart series values plot relative to last series

I'm trying to use Ant Design charts to plot an area chart with 3 series - actual, target and forecast. For some reason, the chart plots the series relative to the last item in the array, rather than relative to the x axis. I tried setting the startOnZero: true but that didn't help.
See below example:
In this example, the target is 220 and the actual is 1558, but the target point is higher on the y axis. Recreated:

If we put the 'Target' values to the bottom of the data array, it works fine for some reason:

By default it creates a stacked chart. You can set isStack to false.

Prevent Recharts Tick Marks from Overlapping

I am developing an application which allows a user to select dynamically queried data which can then be used in Recharts visualizations. There are certain edge cases where the default formatting / rendering within recharts produces an ugly result. For example, if there are many unique values passed to the <XAxis /> component then the chart produced will likely have overlapping text for the ticks.
There does not seem to be any good "render as many ticks as possible, without overlapping" option described in the documentation. These appear to be the only options:
Render all ticks (obviously leads to too many ticks)
<XAxis
dataKey={xAxisField.name}
name={getXAxisLabel(xAxisField, chartType)}
tickFormatter={
getMetaDataType(xAxisField) ===
"DATE"
? tickEpochFormatter // force numbers to be displayed as 'YYYY-MM-DD'
: tickNumberFormatter
}
allowDataOverflow={false}
ticks={xValues.sort()} // gets all of the values
interval={0} // display all of values, instead of the default 5
angle={-90} // force text to be 90, reading towards the graph
textAnchor="end" // rather than setting "dy={50}" or something
>
Render only the start / end / start & end, which depends (seemingly) entirely on the width of the text, prior to rotation.
<XAxis
dataKey={xAxisField.name}
name={getXAxisLabel(xAxisField, chartType)}
tickFormatter={
getMetaDataType(xAxisField) ===
"DATE"
? tickEpochFormatter // force numbers to be displayed as 'YYYY-MM-DD'
: tickNumberFormatter
}
allowDataOverflow={false}
ticks={xValues.sort()} // gets all of the values
interval="preserveStart" // ensure that everything can be read, giving preference to the "left"???
angle={-90} // force text to be 90, reading towards the graph
textAnchor="end" // rather than setting "dy={50}" or something

Hardcode the number of intervals to ensure a maximum? I'm not sure if this is a viable option since I would need to know how many ticks are truly overlapping. Just seems like a crude approach.
Is it even possible to have Recharts render as many things as possible, even if they are rotated 90 degrees, and then selectively choose what has enough space to display? Is it possible to have the angle property dynamically update based on the length of the tick mark texts?

Here's a picture of the problematic rendering I want to clean up:
Also, please note that normally I would prefer to stick to the same library that I have been using, but if another library is better suited for this use-case, I would like to consider switching!

I had the same problem, ended up removing the interval property which set the ticks to be sort-of-dynamic but had only 4 or 5 ticks.
So I set the minTickGap to some negative value. the result was that more ticks appeared on the axis
<XAxis dataKey="date"
angle={45}
dx={15}
dy={20}
minTickGap={-200}
axisLine={false}/>

Highcharts Bar Chart - Labels Not Appearing in Bar

I've been playing around with a highcharts bar chart and noticed some strange behavior. If I have a long name in the x axis (the categories), and if I have labels enabled to show up on the bars, not all the labels will appear. If I remove the long x axis name, then the label that wasn't appearing on the bar before will suddenly appear. I have a working Jsfiddle example here:
https://jsfiddle.net/p55t0bmf/ (notice label isn't appearing for one of the bars, should say 5 but nothing is there)
I placed a long name in the categories section to trigger this behavior:
xAxis: {
categories: ["LONG NAME THAT WILL BREAK US"]
}
Does anyone know why this would be happening, and is there a way to fix this behavior (without resorting to short x axis names of course)?

Set allowOverlap to true. When you have longer xAxis labels, then you have less horizontal space. Labels have padding which can overlap and hide some of them. Anyway, your demo works for me exactly the same way with or without long xAxis category.
Demo with all labels: https://jsfiddle.net/p55t0bmf/1/

stacking option cause this problem. If you set the stacking, then highchart change the label opacity automatically.
Solution : Remove stacking options from chart, if you dont need or write css to override label opacity.

nvd3 - can't showXAxis(false) if xAxis is visible

I'm trying to make a toggleable axis using nvd3s charts, specifically the line chart example. After running this example, opening the console, and typing chart.setXAxis(false) the x axis does not hide. Is there some documentation or some reason why this isn't working? It doesn't seem to work for any boolean either.. once it's true, it's not changeable to false.

setXAxis just tells the chart function whether or not to draw the axis when it draws the chart, it doesn't do anything to the existing axis. You'd be better off just selecting the axis directly and changing its visibility style.
Given the class names that NVD3 uses for it's axes, to hide the x-axis you would use:
d3.select("g.nv-axis.nv-x").style("visibility", "hidden")
That hides the axis, but doesn't delete it, so you can easily re-show it again (without updating the chart) with the same select statement but visibility style visible.

Prevent Flot Chart from repeating ticks while alignTicksWithAxis is set

Flot chart is repeating ticks on right Y axis when:
alignTicksWithAxis:1
I want to align both axes but hide repeated tick values.
http://jsfiddle.net/AUrfY/20/
Is there something in the API i have missed or i have to check thicks before painting and hide duplications.

Set the tickDecimals option to 2 to get reasonable labels for the right y axis (see this updated fiddle).
The label values are not really duplicated, but they are rounded so that they seem so.
