Y Axis Label - text

[Gregor Suttie]

I have my grid working nicely with x and y values as I want - I just want to add a label on the Y axis to signify what kind of data it is - for example say the graph showed money id like a y axis of £, if the y axis was showing temperature data id like to show centigrade.
Note this label im talking about isnt the actual y axis just a textual label to show what the values relate to.

Cheers

Hi Gregor Suttie,

You can change your Y-Axis format by using the CustomFormat property like this:

radChart.PlotArea.YAxis.Appearance.CustomFormat = ("#£");

Alternatively you could assign the currency formatter, which will automatically format the label value according to user's local:

radChart.PlotArea.YAxis.Appearance.CustomFormat = ("C");

More about label values can be found here.

Hi there

On the y axis i have values going from 0-100 as an example. I dont want a label next to each value, I just want to have one word Units next to the values.

            100
            90        
            80
            70
            60
Units    50
            40
            30
            20
            10
            0

Like so, how can I accomplish this.

Its ok I have managed to work it out - I wasnt setting the visibility to true - it must default to false.

How would I got about just appending a '%' to the end of the value of the Y axis label?  Trying ("#%") multiplies by 100 and then appends the % this is not what I want.  I just need to append a % to the end of the value being displayed.

I got it working by adding:

void comparisonChart_BeforeLayout(object sender, EventArgs e)
{
    foreach(ChartAxisItem item in comparisonChart.PlotArea.YAxis.Items)
    {
        item.TextBlock.Text += "%";
    }
}

to the code, but this seems ugly and unnecessary.  Especially since I had to declare the chart at the class level so I could access it in the event handler.  Is there an easier way of doing this?

Hello Nathan,

Try using the following approach which should do the job and only add a "% sign at the end your Y-Axis labels:

radChart.PlotArea.YAxis.Appearance.CustomFormat = ("#\\%");

I am using the Escape character in order to achieve this, which causes the next character to be interpreted as a literal rather than as a custom format specifier.

Thanks, that was helpful. However, I ran into two subsequent problems:

1. "#\\%" results in, for example, "100\%". I'm sure everyone can figure out to take out the extra "\".

2. For the 0% on my chart, it was defaulting to no label. With the custom format that became "%". The final custom format for me was: "#\%;;0\%". Semicolons separate formats for positive, negative, and zero values, respectively.

By the way, I ran into these issues trying to make a StackedBar100 chart with Y-values that don't add up to 1. I like how the RadChart automatically labeled the Y-axis from 0 to 100, but it would be nice if it were 0% to 100% instead.

Hi Chris,

Thank you for your feedback.

I am glad you have found the appropriate solutions to the issues you have faced. Regarding the format used for labeling the axis, this is the default label format used by the control and as you properly mentioned using a custom format solves this.
