mpandroidchart

问题 I have tried figuring this out, but it doesn't add up. The data doesn't appear as it should. First I generate dummy data. This is done async because I need time between the calls to System.currentTimeMillis to get some spacing between them. (Look aside the crappy code here, this is just debug data that will not be in the release. Using Thread.sleep on the main thread is a bad idea considering ANR's) public class AsyncGeneration extends AsyncTask<String, String, String>{ public AsyncGeneration

问题 I have dataset values at range [0-10000]. And I want to see range [500-600] at chart with automatically calculated scroll and zoom values. How it can be done in MPAndroidChart? Is there any method to setXRange(leftXValue, rightXValue)? 回答1: First set the max visible range. So if you want to display the range of 500-600, set a max visible range of 100 mChart.setVisibleXRangeMaximum(100); than you have to move your view so that the values are visible from the 500th position mChart.moveViewToX

问题 I am developing a simple Android app which shows a dataset of flot numbers on a linechart. I am using MPAndroidChart and thanks to it I am able to manage my custom linechart and its style. However, I am trying to add a String Label in order to label both the domain (x-axes) and the range (y-axes) of my linechart, as shown in the picture below. Any suggestions to do it using MPAndroidChart? 回答1: Actually, what I need it is not supported by the MPAndroidChart. Hence the only way to do that is

问题 Currently trying to implement a HorizontalBarChart using MPAndroidChart. However, there are too many bars and they won't all fit on the screen. HorizontalBarChart will scroll only if I zoom in, but will never go past what was already on the screen. Not sure if this is an XML problem (I have the HorizontalBarChart in a Relative Layout, tried ScrollView but didn't work) or if there's already an implementation like chart.enableScroll() (which I have tried, and it doesn't work). 回答1: You can use

问题 I'm displaying a custom legend for a PieChart in MPAndroidChart however, .getColors() and .getLabels() are now deprecated. I've been using them to get an int array and string array respectively but I can't seem to find a direct alternative. Am I missing something obvious? What should I now use instead? Thanks! Legend legend = mChart.getLegend(); legend.setEnabled(false); if (legend.getColors() != null) { int colorCodes[] = legend.getColors(); String labels[] = legend.getLabels(); ArrayList

问题 I have an issue with the BarChart and labels. The labels count is not correct. Even if I put a value directly: xAxis.setLabelCount(5,true); but what I get is only 4 labels. When I put 6 it becomes 5. It seems there is a bug. Also the last item of the labels ( I am using a simple ValueFormatter) does not appear. If the number of labels equals the number of bars it repeats the first one twice even though I use the xAxis.setGranularity(1f); xAxis.setGranularityEnabled(true); and the x values for
