Question on using TeeCharts

[tcoates]

I am playing (testing) other charting components and currently looking at TeeCharts (unit uniTeeChart (from 2014?)). I was able to build and install the component into Delphi XE10.1. Then wrote a small test program. I have added screen from a small demo program I wrote. I want to know how to

 

1. only show values 1, 2, 3 (and not 1.5, 2.5, 3.5) on the y-axis

2. remove shadows

3. remove the rounded border from the chart component

4. etc

 

Can someone give some advice how to do this? Thanks in advance.

Hi,

 

** 1. only show values 1, 2, 3 (and not 1.5, 2.5, 3.5) on the y-axis

 

As a variant of the solution, you can use this approach for now I think,

 

"UniChart" -> ClientEvents -> ExtEvents -> Ext.chart.Chart [chart] -> function chart.beforerender:

function chart.beforerender(sender, eOpts)
{
    var me=sender.axes.items[0];
    me.majorTickSteps=1;
    me.minimum=0;
}

Best regards,

2. remove shadows

 

Have you tried this property ?:

 

UniChart -> Shadow

[tcoates]

adding ext function...

 

function beforerender(sender, eOpts)
{
  var me=sender.axes.items[0];
  me.majorTickSteps=1;
  me.minimum=0;
}

 

gives error d.el is null

 

ALSO... shadow is not a property of a UniTeeChart? Is there a more recent version? Or are you doing this via some other method?

[Sherzod]

adding ext function...

 

function beforerender(sender, eOpts)

{

  var me=sender.axes.items[0];

  me.majorTickSteps=1;

  me.minimum=0;

}

 

"UniChart" -> ClientEvents -> ExtEvents -> Ext.chart.Chart [chart] -> function chart.beforerender:

function chart.beforerender(sender, eOpts)
{
    var me=sender.axes.items[0];
    me.majorTickSteps=1;
    me.minimum=0;
}

And which edition and build are you using?!

[tcoates]

Using...

 

- Delphi XE10.1

- TeeCharts is version bundled with Delphi XE10.1

- unigui 0.99.96.1341

- uniTeeChart is from link in forums but created in 2014.

 

the events that you refer to is available for TUniChart but NOT TUniTeeChart. see attached image..

 

[Sherzod]

- unigui 0.99.96.1341

 

First of all try to upgrade to the latest version, build

[tcoates]

after upgrading to release candidate 1391, I then had to rebuild/install UniGui Teecharts into 10.1.... it appear component palette.

 

the chart can be added to a form. But now when I run the web application I get an EReadError with message 'Error reading UniTeeChart1.Title.Text.Strings: interface not supported"

 

It was working before I upgraded to the release candidate?!?
