GraphView is not updated when new data is added

Question

I have a GraphView that is not updated when new data is added, it changes the Y value to accommodate for the new data, but it doesn\'t draw them, here is the co

Answer 1

For changes to take effect, you need to call:

graphView.onDataChanged(false, false);

instead of graphView.redrawAll() in the View.OnClickListener implementation. You must play with the parameters to ensure the best performance, take a look at the javadoc in the source code:

/**
 * Call this to let the graph redraw and recalculate the viewport.
 *
 * This will be called when a new series was added or removed and when data was appended 
 * via {@link com.jjoe64.graphview.series.BaseSeries#appendData(com.jjoe64.graphview.series.DataPointInterface, boolean, int)}
 * or {@link com.jjoe64.graphview.series.BaseSeries#resetData(com.jjoe64.graphview.series.DataPointInterface[])}.
 *
 * @param keepLabelsSize true if you don't want to recalculate the size of the labels. 
 *                       It is recommended to use "true" because this will improve 
 *                       performance and prevent a flickering.
 * @param keepViewport true if you don't want that the viewport will be recalculated.
 *                     It is recommended to use "true" for performance.

public void onDataChanged(boolean keepLabelsSize, boolean keepViewport) { /*...*/ }

No need for Thread/Runnable at all.
