When I run this function the queryTagHistory keeps bringing back an empty list, or at least the rowCount is 0.
status = system.tag.queryTagHistory(["histprov:scada:/drv:tops scada:default:/tag:" + unit + "/status"], returnSize = 30, aggregationMode = "MinMax", noInterpolation = True, ignoreBadQuality = True)
ind = system.tag.readBlocking(['[default]' + unit + '/StatusIndicator'])[0]
ds = []
i = 0
for i in range(status.rowCount):
color = Units.GetColor(status.getValueAt(i, "intvalue"), unit)
label = GetLabel(ind.value, status.getValueAt(i, "intvalue"))
data = {"Time": {"style": {"classes": color}, "value": status.getValueAt(i, "timestamp")}
,"Status": {"style": {"classes": color}, "value": label}}
ds.append(data)
caller.props.data = ds
The string for the history should be good, I use a similar one in a graph in the project and it works fine. Any thoughts?Thx, jake
