override which series appears in legend

Post by WCantrall » Tue Apr 15, 2014 4:57 am

Is there a way to exclude a series from appearing in the legend? It must remain visible.

I've just added it to the wish list to be implemented in future releases:

Has this been implemented yet?

We're porting some TeeChart_PHP scripts to Javascript / HTML5 and rely on it quite heavily. Happy to test a beta version, as our system won't be going live immediately.

Alternatively, is there a way to override a legend draw method/event?

Kind regards

Mark

Hi Mark,

I'm afraid it hasn't been implemented yet.
I've incremented the issue Importance so it can be reviewed asap.

I've implemented a crude "showInLegend" into javascript version 2014.07.31.1.7 (attached) if that's of any help to anyone?

Hopefully it can be tidied up adopted in the main source :wink:

Hi Mark,

I've removed the attachment in your post because it contains a the TeeChart sources.
We'll study your implementation and we'll be back to you here asap.

**** EDIT ****
For those customers interested in the implementation Mark has just proposed, I'll try to explain it here:
1. Initialize the property at Tee.Series:

Code: Select all

Tee.Series=function(o,o2) {
  this.chart=null;
  this.data={ values:[], labels:[], source:null }

  this.yMandatory=true;
  this.horizAxis="bottom";
  this.vertAxis="left";
  this.showInLegend=true;	//AMJ: added ShowInLegend
  //...
2. Add the appropriate condition at drawSeries:

Code: Select all

  this.drawSeries=function(index,order) {
    var s=chart.series.items[index];
    if ((this.showHidden || s.visible) && s.showInLegend) {	//AMJ: added ShowInLegend
      this.drawItem(s.titleText(index),s,order,true);
      return true;
    }
    else
      return false;
  }
3. Change itemsCount accordingly:

Code: Select all

  this.itemsCount=function() {
    //...
    if ((st==="values") && (result>0))
       result=ss.firstVisible().legendCount();
    else
    {
      if (((st==="auto") && (result>1)) || (st==="series")) {    //AMJ: added ShowInLegend - remove count where not showInLegend?
        var t;
        for(t=0; t<ss.items.length; t++)
          if (!ss.items[t].showInLegend) result--;
      }
      else
      if (result==1)
        result=ss.firstVisible().legendCount();
    }
    //...

There have been two releases of Javascript/HTML5 since this post, and it's not been implemented in the core.

Any problems with the implementation? it matches VCL/PHP which we also use.

Slightly bored of continuing to have to update the new releases!

Hello,

Note we decided to change showInLegend for legend.visible.
So with the next update you'll be able to do:

Code: Select all

Chart1.series.items[0].legend.visible=false;
