由 元气小坏坏 提交于 2019-12-08 07:53:34

The only problem I have is I need to have the x and y axis printed (i.e) L shape on the left and bottom of the graph. I want the X values (thats passed to LineData) to be printed at the bottom of the graph (x-axis) and I want to set minimum and maximum value for the y-axis and the graph should be adjusted based on this min and max value. If I uncomment Line 1 part and pass true /

Swift chart library. How to display X axis dates in a right places

问题 I am currently using MPAndroidChart for my application. In one scenario, I show three datasets within one linechart and when I click on the line on the graph, I get to show only one Tooltip at a time. Instead based on the cross hair position, I would like to show individual tooltip for all three datasets. I have gone through many other questions here and I couldn't find exactly what I am looking for. This is a sample screenshot of my required output. I would like to know if this is possible

how to set values for xlabels and ylabels in mpandroidchart

由 我的未来我决定 提交于 2019-12-06 14:05:42
I am using mpandroidchart android library. I am implementing line charts. Here can i set the x and y labels on my own? currently it is adding the values based on the dataset provided to the chart. Can you please give some idea on this? You have to use a formatter on your axis object. There is two kind of formatter XAxisValueFormatter and YAxisValueFormatter. This the code i used to change the X label number with suffix "h" for hours : //get reference on chart line view LineChart chart = (LineChart) pActivity.findViewById(R.id.chart); //set formater for x Label chart.getXAxis()
