问题 I have two line graphs that show complementary data over the same time period. Is there any way to send any touch events received by one graph to the other?

So if a user swipes left 'n' units on the top graph, the bottom graph will automatically scroll left 'n' units to match. 回答1: Zooms can be done with the current MPAndroidChart release, for scrolling check out or wait for my

问题 I am using MPAndroidChart for charting. I am building a line chart which has multiple dataset objects. From the examples provided by MPAndroidChart I can observe that multiple dataset objects can be drawn in the same line chart but with the same number of points (y-values) and those y-values referenced to the same x-values. What happens if I want to draw multiple dataset objects in the same line chart with different number of points (y-values) referenced to different x-values for each one?

问题 I'm using the MPAndroidChart and am really enjoying it. A 'little' need I have is that I can put null values to the 'entrys'. I'm monitoring the apache conections on servers of my system, and I would to see if they is down (where I put the null value) or if they just no conections (0).

问题 How can I obtain the corresponding x-axis value (xIndex) of a pixel point in a ScatterChart? I have been looking through the source code of the library and I think that one of the methods below (which I copy/pasted from the source code from the library here) can help. It seems getValuesByTouchPoint is the correct method but I don't know how to use it. /** * Transformer class that contains all matrices and is responsible for * transforming values into pixels on the screen and backwards. * *
