I built a graph using MPAndroidChart, but there is a problem - values on x-axis overlap.
Is there a way to fix it? Something like a margin between x-axis values?
It's been a while since you've posted your question and probably by now you found your way around this problem, however, I'm posting this answer for anyone else who has faced this issue.
Setting
chart.getXAxis().setSpaceMin(0.5f);
would add space between the X-axis line and the chart itself. you can also use
chart.getXAxis().setSpaceMax(0.5f);
for adding space between the last value and the right X-axis of the chart.
Here is an example of a normal chart and this one is a chart
with min and max space of 1.5.
By the way, I'm using MPAndroidChart V3.0.2.
Try
XAxis xAxis = chart.getXAxis();
xAxis.setSpaceBetweenLabels(int characters) //Sets the space that should be left out between the x-axis labels in characters, default: 4.

I ma using MPAndroidChart bubble chart. when I run the app it shows x axis values hidden. like I have x-axis label January, February, march, April, may,june. but when app run it shows January , April
and June. on double tape on label it zoom the chart and show hidden labels. I want to show all in a sequence so that user troll horizontal and view all. no need to double tap
You can determinate the numbers of labels to display. This prevents them from hiding automatically.
XAxis xAxis = bubbleChart.getXAxis();
xAxis.setLabelCount(data.length);
Not sure why would you do that. The library does a great job in automatically deciding how many labels to show on either X or Y axis to make the chart nice and readable.
If the chart is narrow, it might happen that your values will overlap, that's why the library skips a few, to make the chart look good.
If that still doesn't help, you can play around with the spacings between axis labels - check out the library's documentation for these specific items
Other solution may be to rotate the labels of the X axis with the help of
xAxis.setLabelRotationAngle(35);
I found the solution after expanding MP Android Chart documentation.
you can do so set thee labels to skip 0. It will skip no label from xAxis.
XAxis xAxis = bubbleChart.getXAxis();
xAxis.setLabelsToSkip(0);
I am working and android chart library using MPAndroidChart .
I am using HorizontalBarChart to display chart.
Please see the attached image and I want do decrease x axis width or want to display x axis text in two lines is there any way to this ?
Any help will get appreciate.
There is currently no way to draw the x-axis labels in multiple lines.
What you can do to decrease the space the labels consume is to simply provide shorter labels. A axis label of the length you are showing above is too long for a chart to be easily readable anyway.
I have an issue with x axis labels overlapping. Is there any way to set the spacing between the values to prevent this?
Thanks

I solved the issue by setting the max x range value to be a small number e.g. 3. This forced the data points to be more spread out which in turn forced the x axis labels to be more spread out.
You could use
multiRenderer.setBarSpacing(double spacing);
I think this would help.
I'm having trouble getting AChartEngine to center the actual visible axises on Origo instead of having them along the left- and bottom of the chart.
I need to have the axises like so:
Any ideas?
(This question is similar to question #2 [2]: Make x-axis in vertical center using AChartEngine but I thought that a more specific question might get an answer)
I made some modifications to AChartEngine 1.0.0 to make it possible to display axises in the center of the plot.
Use code below to set the axises to center.
XYMultipleSeriesRenderer.setXAxisAlign(Align.CENTER, 0);
XYMultipleSeriesRenderer.setYAxisAlign(Align.CENTER, 0);
XYMultipleSeriesRenderer.patch
XYChart.patch
And here is an example on how it may look
There isn't a better answer than the one you mentioned. Just make sure that you calculate X and Y ranges such as your data fits inside and also make sure that the range you set is centered on the 0 point:
renderer.setXAxisMin(-value);
randerer.setXAxisMax(value);
and the same for the Y axis.
I'm using achartengine to show a temperature graph. on X axis I put dates, to fit them I call setXLabelsAngle(45); this is the result:
As you can see, the labels are placed too high and go over the x-Axis. How could I fix this? I'm already using setMargins(), but labels don't move, only legend does.
This will help:
renderer.setXLabelsAlign(Align.LEFT);
