c#Winform MSChart反向Y轴 [英] c# Winform MSChart reverse Y Axis

问题描述

我在Windows窗体上使用MSChart控件.

我正在尝试使用AxisY.IsReversed = true使 Y轴下降，但仍将X轴保持在底部.默认情况下，当我使用AxisY.IsReversed = true时，X轴会上升到顶部.然后，我尝试设置AxisY.Crossing = Max以将轴翻转到Y轴的最大末端(在底部)，但不会移到X轴以下，而只能移到正上方. /p>

请帮助我！！！！！

解决方案

您描述的行为与Microsoft演示项目中显示的行为相同.我相信没有任何调整可以使X轴的标签仅显示在X轴的下方，因为没有与Axis.LabelPosition属性类似的东西可以指定标签应该在该轴的下方.

如果您指定chart1.ChartAreas[0].AxisX.IsMarksNextToAxis = false;，则标签将显示在图表的顶部，而不是所需的底部.

您唯一可以使用的调整是不设置 AxisY.IsReversed = true;，而是将所有Y值设置为*-1(将它们设置为负数).然后使用LabelStyle.Format将负数格式化为正数.

chart1.ChartAreas[0].AxisY.IsReversed = false;               
chart1.ChartAreas[0].AxisY.LabelStyle.Format = "##.##;##.##;##.##";

I am using the MSChart control on a Windows form.

I am trying to have a descending Y axis by using AxisY.IsReversed = true, but still keep the X axis on the bottom. By default, when I used AxisY.IsReversed = true, then the X axis goes up to the top. I then tried the setting the AxisY.Crossing = Max to flip the axis to the maximum end of the Y axis (which is at the bottom) but it won't go below the X axis, it only goes as far as just above it.

Please help me!!!!!

解决方案

The behavior you describe is the same behavior as shown in Microsoft demo project. I believe there is no tweak to make labels of X axis simply appear under the X axis, as there is nothing similar to Axis.LabelPosition property, that would specify, that labels should be under the axis.

Either when you specify chart1.ChartAreas[0].AxisX.IsMarksNextToAxis = false;, then labels appear on top of the chart, not on the bottom as desired.

The only tweak you can use, is not to set AxisY.IsReversed = true;, but make all your Y values *-1 (make them negative). Then use LabelStyle.Format to format negative numbers as positive.

chart1.ChartAreas[0].AxisY.IsReversed = false;               
chart1.ChartAreas[0].AxisY.LabelStyle.Format = "##.##;##.##;##.##";
