MPAndroidChart-第一栏和最后一栏显示不正确 [英] MPAndroidChart - First and last bars not rendering correctly

问题描述

1. 在条形图中，我正在创建的第一行和最后一行始终被切成两半(即使我添加了其他条形).这也会导致条形上方的值不正确.我把它夸大了.

1. In the bar chart I am creating the first and last rows are consistently being cut in half (even if I add additional bars). This also causes the values above the bars to be out of place. I am inflating this within a fragment.

轴也仅增加0.9而不是1.要解决此问题，我需要实现AxisValueFormatter接口吗?

The axis are also only increasing by 0.9 instead of 1. To fix this do I need to implement the AxisValueFormatter interface?

代码: .java

chart = (BarChart) view.findViewById(R.id.chart1);

// Chart settings
chart.setDrawGridBackground(false);
chart.setHighlightFullBarEnabled(true);
chart.setDrawBarShadow(false);
chart.setDrawValueAboveBar(true);
chart.setDescription("");

// Settings for X-Axis
XAxis xAxis = chart.getXAxis();
xAxis.setDrawGridLines(false);
xAxis.setEnabled(true);
xAxis.setDrawLabels(true);
xAxis.setPosition(XAxisPosition.BOTTOM);

// Settings for Y-Axis
YAxis leftAxis = chart.getAxisLeft();
YAxis rightAxis = chart.getAxisRight();

leftAxis.setAxisMinValue(0f);
rightAxis.setAxisMinValue(0f);

BARENTRY = new ArrayList<>();

BarEntryLabels = new ArrayList<String>();

BARENTRY.add(new BarEntry(2f, 1));
BARENTRY.add(new BarEntry(3f, 2));
BARENTRY.add(new BarEntry(4f, 3));
BARENTRY.add(new BarEntry(5f, 4));
BARENTRY.add(new BarEntry(6f, 5));

Bardataset = new BarDataSet(BARENTRY, "Projects");

Bardataset.setColors(ColorTemplate.COLORFUL_COLORS);

BARDATA = new BarData(Bardataset);

chart.setData(BARDATA);
chart.invalidate(); // refresh

chart.animateY(1500);

return view;

推荐答案

要回答您的问题:

1. 要正确显示条形，您需要像这样对条形进行调整(不要问我为什么默认情况下未启用它):

1. In order to properly show your bars you need to fit the bars, like this (don't ask me why it's not enabled by default):

chart.setFitBars(true)

您可以在BarChart javadocs中找到更多信息:

You can find more information in the BarChart javadocs:

setFitBars(boolean enabled): Adds half of the bar width to each side of the x-axis range in order to allow the bars of the barchart to be fully displayed.

如果您有CombinedChart，则可以使用

If you have a CombinedChart you could use setSpaceMin() and setSpaceMax() to add additional spacing on both ends of the axis:

XAxis xAxis = chart.getXAxis();
xAxis.setSpaceMin(barData.getBarWidth() / 2f);
xAxis.setSpaceMax(barData.getBarWidth() / 2f);

当前不可能影响轴上渲染的值位置.创建ValueFormatter仅更改显示的文本，而不更改标签的实际位置.

It is currently impossible to infuence the value positions rendered on the axis. Creating a ValueFormatter only changes the displayed text, not the actual position of the label.
