Hi there, I try to use HighCharts in Mango, but when I put the code into a graphical view I get an error: "failed to hide node", but after clicking OK the chart runs fine. What might be the problem?
Problem integrating with HighCharts
Thanks for your response.
Changing jQuery to Prototype solved the problem, but now another one emerged - is there any way to provide data to HighCharts in any (preferrable dynamic) way?
I believe what you are trying to do is possible, but I would caution against this for a few reasons. First it will be cumbersome and isn't something the GraphicalViews module was designed to do. Second we are moving away from Graphical Views and towards our new Dashboards module.
Thanks for your response.
I am thinking about doing in amCharts using Dashboard - it would be much easier, but still there are lots of things going in the code I have no idea about.
What I would like to achieve is to have a chart, which plots temperature from a sensor. I have a PID that communicates with a heater and depending on the phase of heating the target temperature is different and stored in different variable (I know I can put it into one using some scripting, but it is not the point). I would like to know and see when the phase has ended, so the plotting curve of the temperature's phase would end and a next one would start.
Do you think something like this is possible to be done in amCharts?
You can definitely do something like this with amCharts. I'm not 100% clear on where your heating stage value comes from. Is this a data point?
As Joel said, it can be done. I would need to know more about where the values are that you want to plot but the basic idea is that you can either plot data point values directly onto an AmChart or you can bring the data onto the page and manipulate it prior to plotting it. AmCharts has a particular format for the data it will plot so you will need to be familiar with that first.
Thanks you both for replies.
All data i want to plot comes from data points.
I am using 2.5.2., but I am going to switch to 2.6.0 if you are advising so.
About the chart - I would like to have a whole process in one place. My PLC is all about boiling a liquid in some stages which have defined time and temperature, which can be also changed during the process by a user.
User can define number of stages and also change it on-the-fly. Mainly, the data points I am using are: STAGEXTEMP (X for stage number, from 0 to 9), STAGEXTIME (X for stage number, from 0 to 9), NOOFSTAGES (number of stages, can have values from 1 to 9), ACTUALSTAGE (current stage, from 0 to 9), TEMP (current temperature in °C). The funny thing is that stage 9 is obligatory, so if you set NOOFSTAGES to e.g. 2, you get stage 0, stage 1 and stage 9.
The chart I need would plot a series of STAGEXTEMP for a time decared in STAGEXTIME (it counts down to 0 and makes ACTUALSTAGE go +1, then the next STAGEXTIME is counted down) only for STAGEXTEMP and TEMP, but still showing previous stages and temperatures in a different series so it can be differenciated.
The example in the dashboards module in web/tutorials/dataPointChart.shtm will get you started. Once you have an understanding of how that works I can provide a slightly more advanced example that will show you how to manipulate the data.
