Absence or not visible text at axes

[SuperBoss9]

Hello Everyone,

I'm a new user of OpenHantek 6022 so don't know may be this is made by the design but I don't see the axes text (voltage for example) and the lower field values descriptions (I see only the values of some parameters).
Use windows 10 with 3.2.4 OpenHantek.

Looks like a problem with OpenGL. Please do these tests:
Start the program from cmd.exe and check for error messages.
As above, start from cmd.exe, but use the command line option as described there.
Try also option --useGLSL150 to force OpenGL SL version 1.50 instead of the default of 1.20.

EDIT: wrong assumption, this is no issue.

1. An the result is:

2. And result is:

I'm running it at my laptop with AMD processor and Radeon graphics card. Probably do I need to install something with OGL subsystem?

Some remarks:
The message Attribute ... must be set before QCoreApplication is created. can be ignored. The same applies to QObject::connect: Cannot queue arguments of type 'QList' ....
The option --useGLES or -e for short does not work and gives this error: QOpenGLWidget: Failed to create context.
As I do not use windows, I have no further clue - sorry.

I don't see the axes text (voltage for example) and the lower field values descriptions (I see only the values of some parameters).

EDIT: Sorry, viewing your picture above on my big screen I see now that everything is ok. Please check the manual (available from the "Help" menu) for explanation how to read the screen.

How it should looks like?

[Ho-Ro]

I don't see the axes text (voltage for example) ...

As usual on a scope you have to look at the voltage/division, dB/division or time/division settings in the voltage, spectrum and horizontal tabs on the right or on the text on top/button of the screen, e.g. 50µs/div, the screen is 10 divisions wide and 8 divisions high, so the whole screen equates a time of 500 µs. Same goes for the voltage (100mV/div) as well as the spectrum if you will look at it (it uses Hz/div and dB/div).
Because of more than one possible trace on screen you cannot display values directly on the axes.

... and the lower field values descriptions (I see only the values of some parameters).

Please RTFM (read the fine manual), it's available in the help menu.
