title: MQL5 Remove or Reduce dot size of trend line
body: <p>I trying to plot a trend line object on the graph. But I am disturbed by the dots that are appearing on the trend lines. Here is the code:  </p>
  
  <pre><code>bool TrendCreate(const long            chart_ID=0,        // chart's ID

  <p>Now what I am expecting is that the dots on the line should be small or if not available still will do.  </p>
  
  <p>But I am not getting the way out how I can do that. Kindly suggest me.</p>
