Synchronize Axes


Recommended Posts

I have a chart that has an AxisX that is dates.  I am trying to create a

secondary AxisX along the top of the chart that has the values of the points

that are outside of the chart area (where the plotted value is greater than

the max AxisY value). I have created an additional axis, and have

everything working, except the new axis "ticks" do not line up correctly

with the gridlines from the AxisX.

I am using a "Min" value of 0, a "Max" value of the number of rows in the

dataset, and a "Step" value the same as the XAxis step value. If I use the

"Min" and "Max" values from the AxisX, the new axis values do not show up,

because the AxisX "Min" is -1.7xxx and the "Max" is 1.7xxx. The AxisX is

set to "AutoScale=True" and does an "AdjustScale". I have tried removing

these values, and I still cannot get things to line up.

What do I need to do in order to have the new axis line up with the existing

AxisX gridlines?

Thanks,

Eric

When I query the AxisX "Min" and "Max" values after setting the

DataSourceSettings.DataSource to my dataset

".DataSourceSettings.DataSource = m_DataSet_Excel.Tables(0)"

I get the following "Min" and "Max" values

?chart.AxisX.Min

1.7976931348623157E+308

?chart.AxisX.Max

-1.7976931348623157E+308

Even if I do get the "Min" and "Max" values set correctly, will the new axis

object correctly "synch" with the AxisX?

Thanks,

Eric

Are you setting X-Values ? What type of chart are you using (Lines, Bar ?) ?

Some chart types (e.g. Bars) don't support X-Values, the X-Axis becomes

"categorical" and has no Min and Max, it is just a collection of labels, you

can see it as an axis that goes from 1 to <number of points>.

The X-Axis values are set by binding the datasource to the chart.

The chart type is a "Line" chart.

The following code added to a brand new project returns the expected Min and

Max.

chart1.Gallery = Gallery.Lines;

chart1.DataType[0]= SoftwareFX.ChartFX.DataType.XValue;

chart1.DataType[1]= SoftwareFX.ChartFX.DataType.Value;

chart1.DataSource = new TextProvider("d:\\temp\\CfxDataDates2.txt");

textBox1.Text = chart1.AxisX.Min.ToString();

textBox2.Text = chart1.AxisX.Max.ToString();

Can you please provide with a sample program that reproduces this problem.

I tested using the latest SP of Chart FX 6.2

I am still running Chart FX 5.x.  I will try upgrading to 6.2 with latest SP

and see if that resolves the issue. If not, I'll post here for you email

address and send you the project.

Thanks,

Eric

I have tested with version 6.2 with all updates.  Please give me an email

address where I can send a copy of the project.

Thanks,
