在MPAndroidChart上显示其X轴值时，如何不在线图上绘制零值? [英] How to not draw zero values on a linechart while showing their X axis values on MPAndroidChart?

问题描述

我正在使用MPAndroidChart在折线图中显示我的数据.对于每个日期，我都有自己的价值.

这很好用.我现在要做的是不绘制0值，而是绘制2个相邻的非零值(如趋势线)之间的线，同时继续在x轴上显示零值的日期. /p>

我当前的图形:

所需图形应类似于此图形:

如何实现这种行为?

解决方案

我在这里发布朋友的解决方案(工作原理很简单):

1. 创建一个具有0个值的数据集.用透明颜色线绘制它.
2. 创建一个不包含0的数据集.用所需的颜色绘制.

将(1)和(2)放在同一个LineChart上.

它将为您提供 x轴，其中包含x个值，其中 0个值，但不会为它们画一条线.

第二个数据集将显示数据行点，不包含0个值.

I'm using MPAndroidChart to display my data in a line graph. For each date I have its own value.

This works just fine. What I want to do now is to not draw the 0 values, but instead draw the line between 2 adjacent non-zero values (like a trend-line), while keep showing the dates on the x-axis for the zero values.

My current graph:

The desired graph should look similar to this graph:

How can I achieve this behavior?

解决方案

I'm posting my friend's solution here (worked like a charm):

1. Create a dataset with 0 values. Draw it but with line of transparent color.
2. Create a dataset without 0. Draw it with the color that you need.

Put (1) and (2) on the same LineChart.

It will give you an x axis with x values where there are 0 values but will not draw a line for them.

The second dataset will show the line of data points without the 0 values.
