Dynamically adjusting the legend in ViewON - sean@drydencombustion.co.za - 04-09-2018 Good Day I am trying to make the legend of the trend dynamic when I simulate the viewon page it works but when I load it on the eWON it does not work I have attached some screen shots 1. is the ViewON the eWON 2. is simulated 3. Setup Thanks Sean RE: Dynamically adjusting the legend in ViewON - simon - 25-09-2018 Hi Sean, Weird, this may be caused because there is no data yet... Have you tried by displaying data in the chart ? Simon RE: Dynamically adjusting the legend in ViewON - sean@drydencombustion.co.za - 04-10-2018 Hi Simon There is data as when I fix the legend (constants) It shows me the data to the graph, as soon as I go dynamic I get the above problem. RE: Dynamically adjusting the legend in ViewON - charlotteserre - 30-10-2018 Hi Simon, Hi Sean, I have the same issue, did you find a solution ? Thanks ! RE: Dynamically adjusting the legend in ViewON - AngelaT - 30-10-2018 From what I can gather about how the trend objects get created, the problem is that the structure of the trend - legends, background, etc, get drawn when the page is initially loaded. At that time, since your tags are viewon tags, they are automatically 0 and 0 so it doesn't bother adding a legend. When you finally set those values to something other than 0, it's too late. I could make it work for me when I added a javascript section to my page that runs once when the page loads to set those values. Once that was done, then when I changed the values in the page from my number editor, the graph axis changed accordingly. |
