Abstract

In many technical applications there is a need to monitor parameters. For this purpose orthogonal coordinates or parallel coordinates (cf. Fig. 1) could be used, but the monitoring of many (counter: n) different parameters is complicated, inconvenient (cf. Fig. 2, 3) and contains a high level of uncertainty concerning the detection of trends and excursions. Another method to monitor the parameters utilizes an additional time axis and the bird's eye view. The n parameters are allocated to one axis (e.g. x-axis), their values (which may be compressed) are allocated to the second axis (e.g. the y-axis). The time axis (third axis, z-axis) can represent different measurements or values of the parameters, for example referring to different times or units (cf. Fig. 4). This way, to represent parameters and their values respectively, every new data record can be shown in front of the last one which is shifted back by the new data. The bird's eye view permits to get an overview about a certain time or the chronological development of a multidimensional data range.

Visualization and Monitoring of n-dimensional Data Spaces

Idea: Ute Nehring, DE-Dresden

In many technical applications there is a need to monitor parameters. For this purpose orthogonal coordinates or parallel coordinates (cf. Fig. 1) could be used, but the monitoring of many (counter: n) different parameters is complicated, inconvenient (cf. Fig. 2, 3) and contains a high level of uncertainty concerning the detection of trends and excursions.

Another method to monitor the parameters utilizes an additional time axis and the bird's eye view. The n parameters are allocated to one axis (e.g. x-axis), their values (which may be compressed) are allocated to the second axis (e.g. the y-axis). The time axis (third axis, z-axis) can represent different measurements or values of the parameters, for example referring to different times or units (cf. Fig. 4). This way, to represent parameters and their values respectively, every new data record can be shown in front of the last one which is shifted back by the new data. The bird's eye view permits to get an overview about a certain time or the chronological development of a multidimensional data range.

By this means it is possible to look at a n-dimensional data record like onto a 'water surface' and to detect any excursions (low or high) very easily. To support this detection, these excursions can be shown in different or special colors. Now n parameters can be monitored at a glance.
