Any suggestions on how to do it using MPAndroidChart? 回答1: (Turning @Ironman's comment into an answer:) As of MPAndroidChart 3.0.1 this is currently not possible using the API exposed by the library. You will need to add additional TextView outside the chart, or modify the library to your purpose. If you want to modify the library to your own

Also i cant create two different y-axis, one for the bars and one for the lines. Some curious thing is that MPAndroidChart first adds all x-values and after that all y-values and you have no possibility to

问题 I am making a PieChart in android studio but am running into some issues with styling. The size of description (and legend and values are really small). I read the docs about this and it said there i had to use the setDescriptionTextSize() method and that it is available for every chart type. However that method is not resolved for some reason. extra info about project: -the problem occurs in a fragment -my pieChart is built in the "onChildAdded" method because it needs to be created when

问题 I'm a new MPAndroidChart user. The examples I have found on-line and the Wiki here all give the setDescription() prototype as: setDescription(String desc)` However, mChart.setDescription(""); does not compile for me and AndroidStudio->Go To Declaration tells me the declaration for setDescription defined in Chart.java is : public void setDescription(Description desc) { this.mDescription = desc; } And the Description constructor in Description.java does not take a String.
