MPAndroidChart: How to set x axis labels at fixed interval

Question

I am displaying realtime chart which should display values as per second. My X axis is time in second. But I am not able to display fixed time interval in x axis ie. 0,1,2,... so on. X axis value is automatically calculated and time interval between two x values goes to 20 seconds which I don't want. I need your help to fix this.

Any help would be greatly appreciated.

The interval is called "granularity". You can try `mChart.getXAxis().setGranularityEnabled(true)` `mChart.getXAxis().setGranularity(desiredGranularity)`; — David Rawson, Apr 10 '17 at 23:13
@DavidRawson Thank you! hope people don't miss this comment, should've post it as an answer. — Rus_o, Feb 13 '22 at 16:08

Theres an alternative solution to this that will work on the normal MPAndroidChart (iOS or Android). You can manually set the range covered by the axis, by using axisMinimum and axisMaximum properties. You can also set the number of axis labels by using setLabelCount. With a combination of these, you can get even intervals in-between axis labels. For example, with an axisMinimum of 0, an axisMaximum of 100, and setLabelCount set with 5 labels, you end up with a label at the top and bottom of the range (0 and 100 respectively), and 3 labels inbetween, which gives you a fixed gap of 25. Swift 3 code:

chart.xAxis.setLabelCount(5, /*force: */true)
chart.xAxis.axisMinimum = 0
chart.xAxis.axisMaximum = 100

Gives you even intervals : 0, 25, 50, 75, 100.

are you typo? your code minimum = 100 not 0 – zihadrizkyef Nov 16 '21 at 07:39 — zihadrizkyef, Nov 16 '21 at 07:39
oh yes well spotted @zihadrizkyef! – Luke Smith Nov 16 '21 at 13:25 — Luke Smith, Nov 16 '21 at 13:25

You can use a modified version of the library that allows users to tell the graph which labels should be drawn.

See the example below:

leftAxis.setShowSpecificLabelPositions(true);
leftAxis.setSpecificLabelPositions(new float[]{0, 10, 20, 50, 100, 300});

@theLazyFinder you have to use the modified version of the library; https://github.com/philippeauriach/MPAndroidChart/tree/custom-labels – fgueli Oct 17 '17 at 10:40

Have you tried to set the X-Axis values to a fixed number ?

float minXRange = 10;
float maxXRange = 10;
chart.setVisibleXRange(minXRange, maxXRange);
