I spent more than half of my day on it and unable to figure out solution
drawing bar chart using Charts pod facing two problems
Wanna Corner radius bars as mentioned in required Image
wanna bars besides the grid line as in below image
Required
My output is something like this
Output
Two method
override XAxisRender to make offset x grid line. override BarChartRenderer to add round corner
use ChartLimitLine instead of x grid line. and fork Chart and change BarChartRenderer to implement round corner
this is my demo implemented all you want with method 2

I am using the Charts pod for iOS (github here: https://github.com/danielgindi/Charts ) to make a pie chart.
There is a 1 pixel line in between each slice of the chart. I would like to change the color of this line and/or make it thicker. However, I have not been able to find a way to do either of these things. How do I do this?
Here is what I tried unsuccessfully based on what I found in the PieChartView docs:
chart.tintColor = .blue
chart.maxAngle = 5
Its slice spacing between each slice of Pie Chart. If you want to change or increase that space then you can set space using yourPieChartDataSet.sliceSpace = 5.
i think ther are no seprators you can change the background color of your view and set the corner radius to height / 2
In my bar chart the point range is not equally, so I want to draw different widths for bar chart using highchart. However, all the solution is to draw different series. I wonder is there any solution to hack the code and only change the pointwidth inside one series?
Here is a screenshot
The easiest way would be to change width property of a column SVG element.

I am displaying pie chart and drawing labels outside of chart itself. Sometimes I must display odd data, that one point takes up 90% of chart so the rest must "mash up" into remaining 10% of the chart. Everything is okay, but the labels (slice names) are also "mashing up". So I implemented mechanism that "sorts out" those labels not to collide with each other. Now I have a "word cloud" above my chart, since the biggest slice is always facing down, leaving all other slices facing up. That is my problem: I want to rotate the chart so that the biggest value data point would be facing left (leaving me right side of chart for labels).
So my question is:
How I could rotate pie chart around its center by code?
And rotating whole chart view is not an option since labels must remain horizontal.
So i found the solution myself:
you can use this code:
[(SChartDonutSeries*)[[chart series] firstObject] setRotation:-1.570];
To rotate first (the only in my case) DonutSerie by approx -90 degrees with this line of code. I use it in this delegate method:
sChartRenderFinished
I have chart showing time data. I have two points back in time which I need to "mark" in the chart.
I currently indicate these two by plotlines, but would like to show bar, with let's say green and blue bars showing the timespans (for example -13days from now with blue and -90days -> -13days with red).
I would use plotBands, but I can't specify their height and do not want to have them all over the chart.
Is there some way? I saw something about translating pixels and drawing rectangle, but wasn't able to make it work. Also - I zoom a lot in this chart.
You can use Renderer and add custom shape. In other cases, please attach mockup of your goal.

I'm trying to customize a Coreplot graph in many ways I can and the next thing I would like to do is place the X Axis Labels (one that is custom as well) at the bottom of the graph, independent of the X axis' position (whether it's scrolled up or down).
To make it clear, it is similar to giving the labels an offset value of something like 50.0. But offset is not the property I'm looking for since it fixes the labels location relative to the X axis.
Any way this can be done? Or do I have to skip the axisLabels property and place and layer or something manually at the bottom of the graph?
EDIT: Alright, I managed to place an axis on the bottom with CPTConstraints. But it's not on the bottommost. If a plot point is on those levels, the plot line overlaps the labels. I tired padding of the graph but of course, it moves the whole graph, hence the issue persists.
Thanks in advance
Make a second x-axis. Have the first one draw the axis line, tick marks, etc., as normal but no labels. Label the second one and set all of the line style properties to nil so it doesn't draw any of the lines.
Turns out that aside from the graph, the plotAreaFrame property of the CPTGrpah also has paddings. If you give more paddings to plotAreaFrame than that of the graph, the plot will be drawn in a smaller frame and the rest of the graph area will be for you to add what you want (i.e., a second Axis).
Big thanks to #Eric, for trying to answer Every single CorePlot question as soon as possible.
CorePlot does have a lot of customisation than I thought.
