Thank you for writing.
I am afraid that this functionality is not implemented in our Chart for android because the chart elements do not inherit from View because this turned out to be a significant performance improvement. We will definitely add the ability to collapse an axis in a future release however.
Please write again if you have more questions.
Currently, you can simply add and remove series dynamically instead of collapsing their axes. Is it absolutely necessary for all series to be plotted at the same time?
