Hi,I have made a chart on my form.I want to set the scale of x axis as logrithim.I mean that I have several point added to my chart.When showing the chart,I want the x_axis be shown in logarithim scale.How can I do that?

推荐答案

以下是x轴上logrithm的示例代码

Here is the sample code for logrithm on x axis

Dim axisID As VtChAxisId
' Change both x and y axes to Logarithmic scale for 2D
' Line chart.
MSChart1.chartType = VtChChartType2dLine
For axisID = VtChAxisIdX To VtChAxisIdY
With MSChart1.Plot.Axis(axisID).AxisScale
.Type = VtChScaleTypeLogarithmic
.LogBase = 10
End With
Next

我使用了以下代码:

I used the code:

mychart.AxisX.IsLogarithmic = true;
