A computer-implemented method for generating a data visualization using a graphical user interface, the method comprising: displaying graphical images representing a plurality of sets of reaction sites of a chip to the user; selecting, by the user, at least one of the graphical images representing the sets of reaction sites displayed to the user; generating a representation of detected PCR data from the at least one selected set of reaction sites, the representation being a scatter plot, wherein on the scatter plot, data points are displayed indicative of detected results from nucleic amplification, wherein the nucleic acid amplification comprises a first target and a second target and the data points are designated as being indicative of amplification of the first target, the second target, both targets, or neither target, wherein the detected PCR data is fluorescent emission data for the first and second target; and displaying, side-by-side with the representation of detected PCR data, an indication showing a classification status on a position of each individual reaction site for the detected PCR data, the indication being a heat map (410, 510), the heat map referring to the intensity of fluorescence detected across the selected chip, selecting, by a user input by the user, at least one data point of the detected PCR data on the scatter plot by employing an isolation tool to capture a rare cluster, wherein a computer processor processes this user input to output a data visualization that immediately reflects the selected at least one data point on the side-by-side heat map for a selected chip to determine if this rare cluster is located in a region of high data quality and not placed around areas at increased risk of erroneous detection; labeling the at least one data point of the detected PCR data to differentiate the at least one data point from the remaining data points of the detected PCR data as an artifact rather than an actual PCR amplification; and labeling the corresponding at least one data point on the heat map (410, 510) side-by-side with the scatter plot, wherein the corresponding at least one data point is differentiated from the remaining data points of the detected PCR data so that the differentiated at least one data point and the corresponding at least one data point are excluded from further analysis. displaying graphical images representing a plurality of sets of reaction sites of a chip to the user; selecting, by the user, at least one of the graphical images representing the sets of reaction sites displayed to the user; generating a representation of detected PCR data from the at least one selected set of reaction sites, the representation being a scatter plot, wherein on the scatter plot, data points are displayed indicative of detected results from nucleic amplification, wherein the nucleic acid amplification comprises a first target and a second target and the data points are designated as being indicative of amplification of the first target, the second target, both targets, or neither target, wherein the detected PCR data is fluorescent emission data for the first and second target; and displaying, side-by-side with the representation of detected PCR data, an indication showing a classification status on a position of each individual reaction site for the detected PCR data, the indication being a heat map (410, 510), the heat map referring to the intensity of fluorescence detected across the selected chip, selecting, by a user input by the user, at least one data point of the detected PCR data on the scatter plot by employing an isolation tool to capture a rare cluster, wherein a computer processor processes this user input to output a data visualization that immediately reflects the selected at least one data point on the side-by-side heat map for a selected chip to determine if this rare cluster is located in a region of high data quality and not placed around areas at increased risk of erroneous detection; labeling the at least one data point of the detected PCR data to differentiate the at least one data point from the remaining data points of the detected PCR data as an artifact rather than an actual PCR amplification; and labeling the corresponding at least one data point on the heat map (410, 510) side-by-side with the scatter plot, wherein the corresponding at least one data point is differentiated from the remaining data points of the detected PCR data so that the differentiated at least one data point and the corresponding at least one data point are excluded from further analysis.
