I am using MPAndroidChart to show a bargraph in my Android application. My Y axis values range is in between 0 and 30. I need to show Y axis labels from 0 to 5 always on viewport if Y axis values below 5. If exceeds 5, auto adjust the labels and show as usual. Any way to achieve this.
I am embedding a line chart view in android . The plot is drawn over a dataset of three months of stock of an IPO . The chart is drawn nicely but the values on X axis and Y axis gets very clumsy. Is there a way i can set the range of X axis and Y axis . Am using William Chart library to draw the chart.
You can use this to set scale your chart
chartView.setAxisBorderValues(newMin, newMax, step);

I have a problem using MPChart ：
x axis couldn't display the first date，could someone help me？thanks！
You can use the setAvoidFirstLastClipping(Boolean) from your chart to avoid your first and last labels to be truncated.
From the doc:
setAvoidFirstLastClipping(boolean enabled): If set to true, the chart will avoid that the first and last axis label entry in the x-axis "clip" off the edge of the chart or the screen.
I need suggestion on how to limit the MpAndroid CandleStick chart combined with volume bar chart at the bottom so that volume bar max height can be limit to below 1/3 of chart area Yaxis . From the chart attached , this is somewhere Y Max at 3million region viewport in the left Axis. The current combined chart is ruin by the volume bar chart.
Thanks
setVisibleXRangeMaximum(float maxXRange): Sets the size of the area (range on the x-axis) that should be maximum visible at once. If this is e.g. set to 10, no more than 10 values on the x-axis can be viewed at once without scrolling.
setVisibleXRangeMinimum(float minXRange): Sets the size of the area (range on the x-axis) that should be minimum visible at once. If this is e.g. set to 10, it is not possible to zoom in further than 10 values on the x-axis.
setVisibleYRangeMaximum(float maxYRange, AxisDependency axis): Sets the size of the area (range on the y-axis) that should be maximum visible at once. You also need to provide the axis this constraint should apply to.

Thanks for your comment ,I do not think setting XrangeMax or Min will help , it only limit the x-axis down to certain visible display range instead of showing the full range of the dataset points . The chart shown above has about more than 4000 data points , I have narrowed the visible x-range using set chart.setVisibleXRangeMaximum(100) and also chart.moveViewToX(3000) to optimise performance. What I need is some functional procedure to set the max Y-axis (eg left Y-axis) at certain specific offset position , so that the lower portion of the chart could be restricted to the volume bar chart by clipping the specific rectangle viewports. I am not sure if that is possible , narrowing the YVsibleYrange is not what I have in mind. What I would like to have is
That is possible. All you need to do is plot the data against two different axes (as you are already doing), and then set the top space for each axis separately.
Customizing the axis range
setAxisMaxValue(float max): Set a custom maximum value for this axis. If set, this value will not be calculated automatically depending on the provided data.
setAxisMinValue(float min): Set a custom minimum value for this axis. If set, this value will not be calculated automatically depending on the provided data.
setSpaceTop(float percent): Sets the top spacing (in percent of the total axis-range) of the highest value in the chart in comparison to the highest value on the axis.
setSpaceBottom(float percent): Sets the bottom spacing (in percent of the total axis-range) of the lowest value in the chart in comparison to the lowest value on the axis.
More information in the documentation.
To workaround , I have coded the Y axis to be at 1/x1 of Y viewport height to mark the volume bar top at YMAX in the multiple of x1 where x1 variable can be ={3, 4 or 5} float ymax=barDataSet.getYMax(); float ymaxd=(float)Math.floor (ymax*x1); leftAxis.setLabelCount(x1,false); leftAxis.setAxisMaxValue(ymaxd);
I have the whole line chart working. However the fonts are really small for the labels in x axis and y axis and also on the points where it is plotted. I've circled them in the picture in order to let you know what labels I am talking about.
Also I have disabled the zoom buttons, however we can still zoom using our fingers on the screen. When I zoom in the chart gets messed up. How do I not allow any kind of zooming?
You can set labels size in pixels for 2 axis together
renderer.setLabelsTextSize(float textSize)
Also you can set label color, align gor X and Y axis, for example:
renderer.setXLabelsColor(Color color);
renderer.setYLabelsAlign(Paint.Align.RIGHT);
