在Matlab中绘制大型数据集

Question

我试图绘制两个向量，这两个向量有266个元素。我一直收到错误"使用表格/绘图错误。输入参数太多"。我如何绕过这个错误并绘制所有数据点？

runOneVolume = titrationData(1:249, 'runOneVolume');
runTwoVolume = titrationData(1:241, 'runTwoVolume');
runThreeVolume = titrationData(1:243, 'runThreeVolume');
runFourVolume = titrationData(:, 'runFourVolume');
runFiveVolume = titrationData(1:266, 'runFiveVolume');
runSixVolume = titrationData(1:222, 'runSixVolume');
runOnepH = titrationData(1:249, 'runOnepH');
runTwopH = titrationData(1:241, 'runTwopH');
runThreepH = titrationData(1:243, 'runThreepH');
runFourpH= titrationData(:, 'runFourpH');
runFivepH = titrationData(1:266, 'runFivepH');
runSixpH = titrationData(1:222, 'runSixpH');

plot(runOneVolume, runOnepH) %This line gave the error

Answer 1

由于这些是表，您需要提取值：

runOneVolume = titrationData{1:249, 'runOneVolume'};
runOnepH = titrationData{1:249, 'runOnepH'};
plot(runOneVolume, runOnepH) 

或者，试试这个：

plot(titrationData.runOneVolume(1:249), titrationData.runOnepH(1:249))
