Subject: AnalogSignal: Set initial value for the "value at cursor" variable
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=82e7f4b3f640b6f8bfbd094e478cbe344cc8fc11;p=pulseview.git

AnalogSignal: Set initial value for the "value at cursor" variable

Without this, the analog traces show random values after startup
until the mouse cursor enters the application window and the cursor
position updates.
