  1. While Seeq is working towards enhancing our features in the Histogram tool, here are a simple workaround commonly used to create a histogram for multiple signals with display times in chronological order. Step 1: Start by loading all of the signals we want to include in the matrix into the display. Step 2: Create a monthly condition with a property that split the years and months (YYYY-MM) from the initial date format (YYYY-MM-DDT00:00:00Z) using the formula tool. Formula 1 - month_withProperty $monthly = months("Asia/Kuala_Lumpur") //split the years and month
  2. I would like to have the value to show directly on top of my histogram, doesn't seem to be able to do so with the current function. Any advice?
  3. Background: A property can be added to capsules for further filtering and aggregation through Seeq tools, including Histogram. All properties on a condition are stored as string values. This post examines how to add a property to a condition and then how those properties may be used. Adding Properties to a Condition Capsule properties may be used to store important information such as, Product Codes, Batch IDs, and Recipes. There are three functions in Seeq Formula which can add properties to the capsules in a condition: toCondition() - Dedicated function to transform a
  4. Users are often interested in creating pareto charts using conditions they've created in Seeq sorted by a particular capsule property. The chart below was created using the Histogram tool in Seeq Workbench. For more information on how to create Histograms that look like this, check out this article on creating and using capsule properties. Often times users would like to see the histogram above, but with the bars sorted from largest to smallest in a traditional pareto chart. Users can easily create paretos from Seeq conditions using Seeq Data Lab. A preview of the chart that we can
  5. FAQ: We have various conditions that are calculated from signals on a variety of different equipment and assets. We would like to view them in a histogram that is broken out by month, and for each month each asset has a separate bar in the histogram. Example Solution: 1. For three signals, we want to create a histogram that is the total time per month spent above some threshold. In this example, each signal is associated with a different cooling tower Area. 2. We have a condition for when each signal is above it's threshold value. These conditions were created using
  6. I have several histograms set up to evaluate our process performance based on product criteria. It works great, except for two things... Is there a way I can hide histograms like I can with signals and conditions? I want 14 histograms in my analysis, but with them all displayed at once, it's impossible to see the data. Secondly, is there a way to export the histogram data to Excel (or anything Excel can manage)? Right now I am trying to mouse over each bin result and record it, but that is very time consuming.
  7. FAQ: I've got a signal for which the average and standard deviation are believed to be drifting over time. When I view the average and standard deviation in calendar time, it isn't helpful because they are highly dependent upon the production grade that I am running. Is there a better way that I could be viewing my data to get a sense of the drift of the average and standard deviation by production grade over time? Solution 1: Histogram 1. Add your signal of interest and your production grade code signal to the display. 2. Create a condition for all production grades
  8. Hi All, I've got few Scaler values in my data-set (E.g High,On,OFF) , I have convert all of them into Capsule by toCapsule() Function. Now wanted to remove only those capsules which are having "OFF" Status. Regards, Jitesh Vachheta
  9. Hi- I have a process that goes through several different stages during its operation, e.g. 'Stage 1', 'Stage 2', 'Off' etc. I'd like to determine a count or frequency that my process is in each of these stages. What is the best way to do this?
  10. Overview: This technique example explores two methods for assessing equipment operating conditions per unit of time (i.e. total operating hours per week in this example) using Signal from Conditions (Presented as a Bar Graph) and Histogram. The Signal from Condition approach transforms a condition into a new signal using an equation or statistical function (in this case we will use an equation and the “TotalDuration” function). The approach using the Histogram tool allows transforming a signal into a "value" domain. For example, for a given segment of time, plot the distribution of va
  11. Issues with different devices can lead to shutdowns and failures. In this example we want to monitor the duration of each operation mode of an input signal. This example can be used to monitor all the conditions that can lead to inefficient device performance. In order to monitor all operation modes we need to, 1. Create all the modes using Value Search Tool. a. StartUp (input < 75) b. ShutDown (input > 95) c. SteadyState (75 < input < 95) 2. Create a continuous condition called “Mode” comprising all three (s
  12. The histogram tool when aggregated over time can cause some confusion as to what hours of the day the values of the bins reflect. The bin labels that are generated by Seeq reflect the hour of the day beginning at midnight. So for example, 0 = midnight, 2 = 2 AM, 14 = 2 PM, etc. When the display range interval is set to one day beginning at midnight, the histogram bins line up with the signal value quite nicely (see attached screenshot 2). When the display range is not set to begin at midnight, or is set to multiple days, the histogram bins may not appear to line up with the process data (see a
  13. Hi Seeq- Is there a way to create a histogram with variable size bins?
  14. Hi, I have a strange issue when aggregating data in a histogram. I am counting the number of samples for a signal and aggregate by first using "Year" and the using "Day of the Week" as the aggregation type: This gives me the following histogram with a count of 246 samples for monday in 2012: But these data should belong to sunday. I set up another histogram using the following condition as the second aggregation type: The result now looks like this (which is correct): This is for the other days as well. Is there any way to get around this
  15. Hello - I've searched but not found - this seems, to me at least, an abvious question but I can find no way to do it. In the example below (existing_traces.png) I have three traces - If I want to edit e.g. the histogram (number of buckets etc.) I can't see a way of going back to the screen i used to create it in the first place (original_histogram_window.png). If I click on the (i) in the details tab I then see all the underlying code under item properties (properties_pane.png) but what I want to get to is the original screeen of "Overview >>Historgram" where I can change the numb
