轴标题和Axis在Android中的TeeChart之间距离的变化 [英] Change distance between Axis Title and Axis in Android TeeChart

问题描述

我试图改变在Android中的TeeChart轴标题和轴之间的距离。我打一点点周围

I've tried to change the distance between axis title and axis in Android TeeChart. I played a little bit around with

tChart.getAxes().getLeft().getTitle().setCustomSize();
tChart.getAxes().getBottom().getTitle().setCustomSize();
tChart.getAxes().getLeft().getLabels().setCustomSize();
tChart.getAxes().getBottom().getLabels().setCustomSize();

在左轴它的伟大工程，但BUTTOM轴标题停留在相同的位置。任何人都知道一个解决方案吗？

On the left Axis it works great, but the buttom Axis Title stays in the same Position. Anyone knows a solution?

感谢。

推荐答案

恐怕没有一个单一的财产可以设置轴标题和轴之间添加额外的空间。结果
我能想到的，以实现它的更简单的方法是通过增加一定的余量，以图表和手动绘制轴标题在画布上。即：

I'm afraid there isn't an single property you can set to add extra space between the axis title and the axis.
The easier way I can think to achieve it is by adding some margin to the chart and draw the axis titles manually on the canvas. Ie:

    Bar bar1 = new Bar(tChart1.getChart());
    bar1.fillSampleValues();

    tChart1.addChartPaintListener(new ChartPaintAdapter() {

        @Override
        public void chartPainted(ChartDrawEvent e) {

            String leftText = "Left Axis Title";
            String bottomText = "Bottom Axis Title";

            int YMid = tChart1.getChart().getChartRect().y + (tChart1.getChart().getChartRect().height / 2);
            int XMid = tChart1.getChart().getChartRect().x + (tChart1.getChart().getChartRect().width / 2);

            tChart1.getGraphics3D().setFont(tChart1.getAxes().getLeft().getTitle().getFont());
            int leftHeight = tChart1.getGraphics3D().textWidth(leftText);
            tChart1.getGraphics3D().rotateLabel(10, YMid + (leftHeight / 2), leftText, 90);

            tChart1.getGraphics3D().setFont(tChart1.getAxes().getBottom().getTitle().getFont());
            int bottomWidth = tChart1.getGraphics3D().textWidth(bottomText);
            tChart1.getGraphics3D().textOut(XMid - (bottomWidth / 2), tChart1.getHeight() - 20, bottomText);
        }
    });

    tChart1.getPanel().setMarginLeft(10);
    tChart1.getPanel().setMarginBottom(10);

然后，您可以轻松地添加更多的保证金或移动的标题。

Then, you can easily add more margin or move the titles.
