I am using iOS Charts by Daniel Gindi.
I need to draw horizontal stacked area chart (Example). But I cannot find similar charts in examples of the library. I am trying to customise Horizontal Bar Chart like in example. But I cannot to avoid square corners.
How can I draw line instead of bars with squared corners?
Is it possible in this library or I should use another one?
Yes you can.
Use line chart instead ,and set drawFilledEnabled to true.
But the filled area is between line and x axis, so you may need to rotate the chart.

Is it possible to change x-axis label orientation like marked area on the screenshot? I was trying rotate labels with afterCalculateTickRotation but they weren't flipped. Mirror option doesn't work also.

I managed to do what you are asking for but it's not beautiful because chart.js lacks support to do it properly. So I solved it with some hard coded padding.

It's the minRotation and maxRotation you should work with. The labels anchoring point should shift when the rotation goes below zero but they don't. Instead they rotate into the chart but this can be avoided with padding.
A side effect of the padding is that the legend placement broke so i put it in the top instead.
Another unwanted behavior is that the text is aligned to the right. There is an open issue about that: https://github.com/chartjs/Chart.js/issues/4193
I have a use case where i want to plot area charts along with bar/line charts. I am able to do that with no issues.
The problem I am now facing is the overlapping of colors when say, bar and area are plotted together. (Sample is below). In this, as you can see, the colors of the bar are getting overcast due to the area plotted.
Area + Bar + Line
What I would like to do is plot the area canvas as background and others as foreground. (PS: I tried by changing the sequence of plotting the series, which changes the sequence of canvas also, but the effect remains the same)
Is there a way to do that ?
I've got a stacked bar chart with legends, but depending on the data selected, it becomes unreadable because of the space added around the bars and the series and the fact that the outer horizontal axis label won't rotate. I've tried as many things as I can think of, but nothing alters the spacing or the rotation on the outer axis. Picture 1 gives you an idea of what I mean. Main thing that would probably help is the rotation. Using VS2012 but not inline code. Any help appreciated.
I am using Dimple.js to plot several data series and I need to add a candlestick or hi/lo series on to my existing chart. After some analysis, I have found two possible approaches to do this:
1) Use the floating bar option in Dimple.js. Since the "widths" (heights on the chart, but widths for the floating bar) would be all different, I would need a different data series for each candlestick. This feels like a hack, but the one advantage is that this would be using Dimple to do all the rendering. I would probably not go this route unless some had a thought on how to make this less of a hack.
2) Drop down to D3 to draw lines between the points. I can use Dimple.js to graph both the top and bottom elements of the candlestick, then use D3 to draw the line between the points. I would do a selectAll() on one of the series, and then draw a path to the related point in the other series.
If there are other suggestions on an approach, please let me know. Thanks!
You can use this example to build candlestick charts using d3.js
In Qlikview 11 I managed to set up (amongst others) a nice scatter chart without any major problems. Now I would like to be able to zoom into a region in that chart. Intuitively this could be accomplished by selecting a rectangular region with the mouse. Incidentally this works fine in "regular" line or bar charts. The new x and y axis regions correspond to the selected rectangle. However this does not happen with my scatter chart. I suspect this has something to do with the way dimensions are handled in scatter charts. For easier understanding I appended to screen-shots of the status quo - or how I don't want it to be.

From what it looks like, I would guess that the scatter plot has hard coded axis max and mins. Check the "Axes" tab under chart properties, and uncheck the scale boxes. That should allow the chart to zoom in.
