Fix (freeze) y axis for Android GraphView package

Question

I need a way to fix the y axis for the graph view package. I am showing real time frequency spectra but it is not possible to visualise the data properly as the y axis adjusts to the current largest value. Please advise. I will offer a bounty to any answer that easily solves my problem.

Answer 1

If you know the range if Y axis, the method setManualYAxisBounds(max,min) can be used. For example, if you are using a sin function,

graphView.setManualYAxisBounds(1,-1);

Or if yours is a percentage graph,

graphView.setManualYAxisBounds(100,0);

If you have the values to be plotted in an array, again the method can be used with the max and min values of the array (with formatting looks neater).
