105 visibility of the legend

[DanielNowak98]

I have added style changes for the legend. However, due to the color alteration, the labels of the individual scopes are hardly readable. Therefore, I have temporarily made them white. The color can still be changed. Furthermore, I have changed the location of the legend. It is now positioned in the top right corner, reducing the risk of covering parts of the plot.

added to Style.cpp:

void SetImPlotLegendProperties() {
  // Legenden-Hintergrundfarbe ändern
  ImPlotStyle &plotStyle = ImPlot::GetStyle();
  plotStyle.Colors[ImPlotCol_LegendBg] =
      ImVec4(0.5f, 0.5f, 0.5f, 1.0f); // Dunkelgrau
}

and to Style.hpp: void SetImPlotLegendProperties();

and this to main:

    SetImPlotLegendProperties();

    addPlots("Recording the data", captureData,
             [&sampler, &xmax_paused](auto /*x_min*/, auto x_max) {
               if (!flagPaused) {
                 ImPlot::SetupAxes("x [Data points]", "y [ADC Value]",
                                   ImPlotAxisFlags_AutoFit,
                                   ImPlotAxisFlags_AutoFit);
                 ImPlot::SetupAxisLimits(ImAxis_X1, x_max - 7500, x_max + 7500,
                                         ImGuiCond_Always);
               } else {
                 xmax_paused = x_max;
                 ImPlot::SetupAxes("x [Seconds]", "y [Volts]");
                 // x and y axes ranges: [0, 10], [-10, 200]
                 ImPlot::SetupAxesLimits(0, 10, -10, 200);
                 // make specific values/ticks on Y-axis
                 ImPlot::SetupAxisTicks(ImAxis_Y1, -10, 200, 22, nullptr, true);
                 ImPlot::SetupLegend(ImPlotLocation_NorthEast);
               }
             });

    ImGui::EndChild();

@DanielNowak98 The github action is failing because the submodule aglio is checked out with the wrong git hash. This version does not contain an function overload so it wont build. To fix this please go into your local branch and checkout the git hash c8c5a07 Then it should work
