I would like it to have the "X and MR Chart for Variables, SixGraph Summary" node to be better customized.
1) In essence the nodes comes with 4 graphs and the histograms are nice to have but it pollutes the screen, we should have the option to play around to mix and match which graphs we would like to show, and have only our momentaneous needs displayed right there available on the fly. Someone goes and playes with the node, ok cool nice feature and then they ask themselves "how do I delete these histograms I don't need 'em... a few moments later... I can't find the option or Oh maybe I can't". So bummer.
2)The X-bar and R-bar charts display on the X axis the data points cronologically from left to right but label as 1, 2, 3, and so forth and so on. We would like to be able to customize the X axis with the actual Date and/or Time for that observation. So that when an analyst sees the chart he/she will be able to identify on the chart exactly the date or time it occurred a certain given point. Instead of going through: "Ok so point number 32, minimizes the screen, goes back to the dataset, finds the 32nd observation and finds out which date it was, but does'nt realize he/she mistakes the 32nd observation for the 31st or the 33rd observation because of not knowing exactly how many lines to count. It's a mess. People do get confused with the silliest things and we can't assume people are paying attention to detail and/or multi-tasking during the process. Displaying date and/or time even though not common would save an analyst time and be more intuitive. Other tools are adding features from other tools and we think the customization would allow a better data visualization during the discover/modelling process.
We did record a macro and created a custom node using R, however that is beyond support's realm, and we don't want our clients doing customization very often otherwise it misses the whole point of using Statistica in the first place.

This is available in the node named SPC Charts. You may have to use multiple instances of the node to get both an X-bar chart and Individuals chart by themselves
After you add the node to a workspace, will see the longer name is SPC Charts with Alarming.

X-axis labeling: You can select which input variable to use as sample identifier and it will be used to label the X-axis. However, if you want to use a separate variable for X-axis labeling, you would have to create a graph customization script to do it.
Identifying sample for a defined point on the graph: The SPC Charts node allows the user to define the step and font size to add more labels, but there is no full solution to this with non-interactive graphs. With Statistica you would typically create an alarm for the condition and output the alarm table which includes the sample ID for tracing. Or you have to output the descriptive stats table which also includes the sample ID for all points.
