In LabVIEW 7. To my knowledge, even if the documentation is somewhat imprecise, zooming and panning work only for the xy graph, and here only provided that the graph control is set to a mode other than indicator. LabVIEW Base. •What are some of the common types of graphs and charts in LabVIEW? List and discuss three of them. I think it can be nice to have the same pause feature as implemented in Labwindows CVI stripchart. Valid values include 0 (Strip), 1 (Scope), and 2 (Sweep). I am using multiple instances of it and simply sending dataHello, I'm not sure if this is possible or not within LabVIEW, so I'm hoping someone in the forum knows if it is and if so, knows how to do it: I've had a few applications come up recently where it would be good to know how to do the following: 1. NI charts, in both LabVIEW and Measurement Studio, have three different modes to scroll data. To solve this, first, we are going to split the dynamic data to extract the datasets and use what we want. A pen simply marks or traces data as the paper unrolls. You will learn how to apply these concepts to the peak detection VIs in LabVIEW and the peak detection functions in Measurement Studio. Because of these changes when you make a change to either the axis or trace attributes the entire strip chart must be refreshed which causes all traces to be essentially replotted. I'm trying to merge two charts from different while-loops. In order to do this, you will need to use a circular array. Maybe I'm missing the point but I cannot find what I'd like. When the plot reaches the right border of the plotting area, LabVIEW erases the plot and begins plotting again. This mode first plots values from left to right.

The scan rate will be variable from 1 scan per second upward. Multisim. Alternatively, you can increase the number of data points in the chart history buffer prior to running the program. You can interpret this data type as a signed, 128-bit fixed-point number with a 64-bit radix. Chart recorders may record several inputs using different color pens and may record onto strip charts or circular charts. We don't need to update the display very quickly probably at 5-10Hz would be sufficient. Select X-Scale->Properties. See all Driver Software Downloads. If the resize operation is repeated to another size and then back to the original size, the axis labels will sometimes. INTENSITY GRAPHS AND CHARTS IN LABVIEW. Strip chart– running data is continuously displayed through scrolling in strip chart.
