I am using MPAndroidChart library for my project.
Is it possible to rotate the labels of the XAxis by 270 degrees so that I can fit more text?
Original answer:
Unfortunately it is currently not possible to rotate the values on the x-axis of a chart to a certain degree / angle.
You will have to implement such a feature yourself.
UPDATE:
As of v2.1.5 this feature is now available:
XAxis xAxis = chart.getXAxis();
xAxis.setLabelRotationAngle(...);
do it simply by
XAxis xAxis=barChart.getXAxis();
xAxis.setLabelRotationAngle(-45);

I have a chart and use mpandroidchart
the shape is as shown below
how can my line be neat and not too sideways?
If you are using version above 3 then you need to modify your xAxis as follows and last two lines of code will solve your issue:
// xAxis customization
XAxis xAxis = combinedChart.getXAxis();
// Following code have no effect but you can change it if required
xAxis.setGranularity(1f);
xAxis.setGranularityEnabled(true);
xAxis.setCenterAxisLabels(false);
xAxis.setDrawGridLines(false);
//xAxis.setXOffset(2);
// Setting maximum limit of xAxis
xAxis.setAxisMaximum(barData().getEntryCount());
// Setting position of xAxis
xAxis.setPosition(XAxis.XAxisPosition.BOTH_SIDED);
// This is used to fix bar width of first bar
**xAxis.setSpaceMin(barData().getBarWidth() / 2f);
xAxis.setSpaceMax(barData().getBarWidth() / 2f);**
I'm not sure but its worked for me.
This error comes from X Axis starting point.
Set starting point as 1.
xAxis.setAxisMinimum(1); // or xAxis.setAxisMinimum(2);
I use MPAndroidChart in my project, today I meet a problem,please look the screenshot.

I know how to implement the left diagram，but I don't know the right how to implement.
I know the answer:
XAxis xAxis = barChart.getXAxis();
xAxis.setPosition(XAxis.XAxisPosition.TOP);
YAxis leftYAxis = barChart.getAxisLeft();
leftYAxis.setInverted(true);
I have created such chart, but problem is that values under xAxis doesn't displays fully, so there should be "2017-08-10", instead I see "20", If I zoom that chart, I can see all data under the xAxis. How to see all values?
I have also tried to change RotationAngle to 25 and 90, but still no results.
XAxis xAxis = chart.getXAxis();
xAxis.setValueFormatter(new MyXAxisValueFormatter(datesArray));
xAxis.setLabelRotationAngle(45);
xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
chart.getDescription().setEnabled(false);
I have also removed xAxis.setLabelRotationAngle(45);But, in that case dates overlap each other.
Set bottom padding to chart using setExtraOffsets like.
setExtraOffsets(float left, float top, float right, float bottom)
When i use xAxis.setLabelRotationAngle(-45); to rotate the labels of the xAxis on a bar chart,it causes the chart to jump up on the charts.BarChart control.
Chart without label rotation
Chart with label rotation
How do i prevent this from happening while keeping the rotation?
I´m using MPAndroidChart 2.0.9 version. I would like to set labels on y-axis from 0 to 100 and display always this range, but i can´t find the chart.setYRange() method.
The range can be customized via the YAxis class.
Here is the documentation: https://github.com/PhilJay/MPAndroidChart/wiki/YAxis-%28YLabels%29
YAxis y = chart.getAxisLeft();
y.setAxisMaxValue(100);
y.setAxisMinValue(0);
You can try to write this:
yAxis.setLabelCount(x)
This code should give you labels in steps of x, assuming you set a min and max value.
Example of my code:
YAxis y = mChart.getAxisLeft();
y.setAxisMaxValue(100);
y.setAxisMinValue(0);
y.setLabelCount(6);
This will give me labels from 0 to 100 in 6 steps, so: 0-20-40-60-80-100.
