Universal design of statistical graphics software Problems

★ a. (R for the longitudinal coordinates of the scale Q from) (9) axes and display scale drawing program and database interface 2 as the general statistical graphics software, mapping data file name, field name, type and other parameters by the user drawing application by dynamically given. Therefore,[link widoczny dla zalogowanych], the application of graphics software should be asked to complete a parameter file transfer parameters of the work (in the direct use of graphics software, interactive way to fill the available files). Parameters Man Received Date:】 998 Ol Bu i first author of a 1960 men who associate professor of Jilin Institute of Technology blunt Volume 20 pieces should contain the following fields: (1) graphics library file name (with path). (2) l set of data sources of a field name. The first N sets of data sources of a field name. (3) Group 1 data show that the data name. The first N sets of data show the data name. (4) x-axis value of the field of field names, () x-axis title. (6) Y axis title (7) Figure Title. (8) graph type (pie, histogram, line ... etc.). (9) map scale (ie shrink or enlarge a drawing ratio of the data. For example, in the amount of the value of the dollar. The map to million units. The data compression should be preceded by the drawing of a million times, here fill in 0. 0001.) (10) data filtering conditions (meaning see 3). (1I) a description of condition variables (meaning, see 3). :: Condition variable M shows 3 data filtering users may wish to meet the given conditions, only selected data for mapping, and the conditions not known in advance. Then the parameter file can be used to pass the conditions and procedures designed to explain the dynamic access conditions variable, according to the conditions filter the data. For example. Suppose that a library file has a field in January YF, users often select the data range mapping by month, then the parameter file AND. YF M or the Switch (9). (3) the # each of the first data screen should be the last before a panel of data in order to avoid the last screen left with only two data affect display, each screen shows the number of data should be variable. For example, if the not more than l5 months remaining data is a screen display, or a screen display 10 data, the next screen and then display the rest.
