XY plot slight visual improvement

Would there be any possibility to slightly customize the standard XY plot symbol more? We have a simple example, attached a xy plot in Paper industry. Tens of measurements on Y-axis and diameter on X-axis. The trends are behaving as expected, when selecting from Scales "Multiple Y Scales". Unfortunately when selecting this, the XY Plot is almost fulfilled with all the Y axises from measurements. The problem now is, that for most of the measurements the Y scale is exactly the same. Would there be even a possilibility to choose to hide the scales themselves? Another question is, that would there be any possibility to set the XY plot so, that when opening the display 95% of the measurements would be automatically hidden, and could be clicked so that the trend is visible if needed?
