  1. Hello Kemi, Thank you for your question. This chart can be created as follows; 1. Calculate the moving range in the formula tool; abs($signal.runningDelta()) 2. Create the monthly condition using Identify > Periodic Condition tool and select a monthly duration. 3. Use Quantify > Signal from Condition tool to find the average moving range over each month. This is “CL” as shown in the video. 4. In the formula tool, calculate the UCL parameter as follows 3.268*$average_movingrange Alternatively, create a new Signal from Condition to calculate the standard deviation of the moving average, and in formula use the following; 3*$stddev_movingrange 5. Add the signals to one lane and align their y-axis. We also have a very comprehensive blog post on creating a Control Chart and applying SPC run rules which may be of interest to you.

  2. Was this a duplicated analysis? If so, I suspect that the IDs you're seeing are associated to items that couldn't be cloned successfully. If this is the case, you should find a journal in the (new) first worksheet of the cloned analysis, which will list items that couldn't be cloned successfully for some reason. Often this has to do with permissions. These items are created in the cloned analysis, but they're assigned placeholder IDs that are serial numbers preceded by an appropriate number of 0s to make a GUID. If that's what happened here, examining the journal on the first worksheet of the analysis should provide clues as to what needs to be fixed before a subsequent attempt at duplication.

  3. Using formulas with trended data (temperature) I created a signal representing the density of a fluid in a vessel. I have reason to believe ambient conditions are impacting the temperature of the liquid inside of a level bridle thus changing the liquid properties. Using level measurements in the vessel and level bridle and the density/ specific gravity calculated for the liquid in the vessel (based on actual vessel temperature) I was able to calculate the density/ SG of the of the liquid in the level bridles based on the variation in level measurement. The equation for density is fairly complicated so manipulating the equation solving for temperature isn't a realistic option for me. Is there a way to have Seeq calculate/ trend a signal representing the temperature when I have a signal representing the solution (density) with temperature being the only variable? The equation I'm working with is shown below. I have the values for all of the constants and I'm wanting Seeq to calculate the value of T.
