How to add a scalor for RtTrend?

Hi, All,

I am a newbie to Photon microGUI programming. I use a RtTrend for ream time
data plotting, however, I could not set its scalor on its axis.

Also, I met another problem. Since I put three RtTrends on a PtDivider, and
hope to plot three data simultaneously. However, when I drag the divider
during its plotting, I found that another RtTrend is affected, and even its
trend will go astray during my draging the divider, this is a big problem
for me, and I still could not find the answer.

Your any kind suggestion will be highly appreciated.

Regards,

Yuhong
