Zoho Charts and Trendiness

Zoho Charts and Trendiness

I'm pretty new to Zoho Analytics, and this is a pretty basic question.

I've created some solid vertical bar charts.  Everything looks the way I want it.  However, I went in and decided I wanted to add a linear trend line to overlay the bar chart.  It did that nicely, but it converted all of my bars to very narrow bars (almost lines).

I can't see a way to adjust the width of the bars in the chart.  I'll attach a couple of screen shots to show what I am getting.  I hope that makes sense.

Thanks in advance for any assistance on this!
