This required sort behavior has been removed in Logger Pro<\/i> 3.5 and newer; to avoid sorting, upgrade to version 3.5 or newer.<\/p>\n
In Logger Pro<\/i> 3.4.6, when plotting the data from one sensor versus the data from another sensor, or if the events with entry points were not entered in ascending order, AND a selection of a portion of the graph is made, Logger Pro<\/i> can have problems performing the curve fit. <\/p>\n
In version 3.4.5 and earlier, Logger Pro<\/i> would silently use a subset of the selected points, and so the fit would sometimes be unexpectedly poor, or the fit might fail with a message that more points need to be selected.<\/p>\n
In version 3.4.6, if the points on a graph are not sorted, any curve fit request will yield only a message to sort the data. On sorting the horizontal axis data, the fit will succeed, and the fit will use all the selected points. <\/p>\n
To sort the data, do the following:
\n1. From the Data menu, choose Sort Data Set –> (data set name)
\n2. In the resulting dialog, choose the column graphed on the horizontal axis
\n3. Select either ascending or descending, and click OK. <\/p>\n
Note that if your data table is sparse, with blank cells due to differing data collection rates on difference sensors, the sort may fail to allow a curve fit. <\/p>\n
Or, if your horizontal-axis column is calculated, the sort will not be allowed.<\/p>\n
In these cases, the workaround is to create a new Data Set with two manual columns. Copy and paste your two columns into this new data set. Sort on the horizontal axis column in the new Data Set; the sort will now succeed, and your curve fit will work. Upgrading to Logger Pro<\/i> 3.5 or newer will avoid the sorting.<\/p>","protected":false},"excerpt":{"rendered":"
