Very often a variable name needs to provide more context. I have found it very useful to use under_scores as a form of punctuation within camelCase to visually connect related variables. Like this: spectrumPlot_x spectrumPlot_y spectrumPlot_drawHarmonics qa_signalDone qa_setLoadedFlag requestTimeout_minValue requestTimeout_maxValue ... and so forth. (Note that the opposite doesn't work: camelCase as a punctuation within under_scores.)
